Relay Mounting Example
Description
Thermal management is a fundamental consideration in the design and use of solid-
state relays (SSRs) because of the contact dissipation (typically 1 W per ampere)�
It is vital to provide sufficient heat sinking, or the life and switching reliability of the
SSR will be compromised�
The SSR-HS-1 heat sink maximizes heat dissipation and helps ensure reliable
operation when properly selected for the specific application� For ease of
installation, all mounting holes are pre-drilled and tapped�
The SSR-TP-1 simplifies installation with a simple peel-and-stick solution, which
does not require messy thermal grease�

Application Data Legacy Solid-State Relays
Definition
A solid-state relay (SSR) can perform many tasks that an electromechanical relay
(EMR) can perform� The SSR differs in that it has no moving mechanical parts� It is
essentially an electronic device that relies on the electrical and optical properties of
semiconductors to achieve its isolation and switching function�
Principle of Operation
SSRs are similar to electromechanical relays, in that both use a control circuit and
a separate circuit for switching the load� When voltage is applied to the input of the
SSR, the relay is energized by a light emitting diode� The light from the diode is
beamed into a light-sensitive semiconductor, which conditions the control circuit to
turn on the output solid-state switch� In the case of zero-voltage crossover relays, the
output solid-state switch is turned on at the zero crossing of AC voltage� Removal of
input power disables the control circuit, and the solid-state switch also turns off when
the load current passes through the zero point of its cycle� Zero cross only applies to
AC switching circuits� DC switching circuits operate at an instant on/off rate�
Advantages
When used correctly in the intended application, the SSR provides many of the
characteristics that are often difficult to find in the EMR� A high degree of reliability,
long service life, significantly reduced electromagnetic interference, fast response,
and high vibration resistance are significant benefits of the SSR� The SSR has no
moving parts to wear out, or arcing contacts to deteriorate, which are often the
primary cause of failure with an EMR�
• Long life (reliability) > 1E+9 operations
• Zero voltage turn-on, low EMI/RFI
• Resistance to shock and vibration
• Random turn-on, proportional control
• No contact bounce
• Arc-less switching
• No acoustical noise
• TTL compatibility
• Fast response
• No moving parts
25
Applications
Since its introduction, SSR technology has gained acceptance in many applications
that had previously been the sole domain of the EMR or contactor� The major
growth areas have come from industrial process control applications—particularly
heat/cool temperature control, motors, lamps, solenoids, valves, and transformers�
The list of applications for the SSR is almost limitless�

Typical Examples of SSR Applications
Application Data (continued) Legacy Solid-State Relays

Using A Temperature Derating Curve
In the example below, a temperature derating curve for a 50 A, Class 6 solid-state
relay is used to determine the maximum allowable load current at an ambient
temperature of 70 °C� A heat sink with a 2 °C/W temperature coefficient is used in
the application�
From the right half of the graphic, the point at which the heat sink coefficient curve
crosses 70 °C is translated to the left half of the graphic until it intersects the
power dissipation vs load current curve of the 50 A, Class 6 relay as shown in the
illustration below:
The result is that a maximum load current of 20 Arms is recommended when using
a 50 A, Class 6000 relay in an ambient temperature of 70 °C when using a heat
sink with a 2 °C/W temperature coefficient�

27
Load Considerations
After improper heat sinking, the next most significant cause of application problems
with SSRs stems from the operating conditions that specific loads impose on an
SSR� Carefully consider the surge characteristics of the load when designing an
SSR as a switching solution�
• Resistive Loads
A load with a constant value of resistance is the simplest application of an SSR�
Proper thermal consideration, along with attention to the steady-state current
ratings, is important for reliable operation�
• DC Loads
DC loads are inductive loads� Place a diode across the load to absorb surges
during turn-off�
• Lamp Loads
Incandescent lamp loads, though basically resistive, require special consideration�
Because the resistance of the cold filament is about 5–10% of the heated value,
a large inrush current can occur� It is essential to verify that this inrush current is
within the surge specifications of the SSR� Also ensure that the lamp rating of the
SSR is not exceeded� This UL rating is based on the inrush of a typical lamp� Due
to the unusually low filament resistance at the time of turn-on, a zero voltage turn-
on characteristic is particularly desirable with incandescent lamps�
• Capacitive Loads
These types of loads can be difficult because of their initial appearance as short
circuits� High surge currents can occur while charging, limited only by circuit
resistance� Use caution with low impedance capacitive loads to verify that the dl/dt
capabilities are not exceeded� Zero voltage turn-on is a particularly valuable means
of limiting dl/dt with capacitive loads�
• Motors and Solenoids
Motor and solenoid loads require special attention for reliable SSR functionality�
Solenoids have high initial surge currents because their stationary impedance is
very low� Motors can also have severe inrush currents during starting and can
impose unusually high voltages during turn-off� As a motor’s rotor rotates, it creates
a back-EMF (electromotive force) that reduces the flow of current� This back-EMF
can add to the applied line voltage and create an overvoltage condition during turn-
off� Likewise, consideration must be given to mechanical loads having high starting
torque or inertia, such as fans and flywheels, to verify that the inrush currents are
within the surge capabilities of the SSR� Use a current shunt and oscilloscope to
examine the duration of the inrush current�
Application Data (continued) Legacy Solid-State Relays
28
Transformers
When switching transformers, consider the characteristics of the secondary load�
These characteristics reflect the effective load on the SSR� In addition, voltage
transients from secondary load circuits can act as transformers and impose on the
SSR�
Transformers present a special challenge: Depending on the transformer flux state
at turn-off, the transformer may saturate during the first half-cycle when voltage is
next applied� This saturation can impose a very large current (10–100 times the rated
typical current) on the SSR, which far exceeds its half-cycle surge rating� SSRs with
random turn-on may have a better chance of survival than a zero-cross turn-on device,
since they commonly require the transformer to support only a portion of the first half-
cycle of the voltage� On the other hand, a random turn-on device will frequently close
at the zero-cross point, and then the SSR must sustain the worst-case saturation
current� A zero-cross turn-on device has the advantage that it turns on in a known
mode and will immediately demonstrate the worst case condition� The use of a current
shunt and an oscilloscope is recommended to verify that the half-cycle surge capability
is not exceeded�
As a general rule, when applying an SSR to a transformer load, select an SSR having
a half-cycle current surge rating greater than the following:
(maximum applied line voltage) ÷ (transformer primary resistance)
The primary resistance is usually easy to measure and can be relied on as a minimum
impedance limiting the first half-cycle of inrush current� The presence of some residual
flux, plus the saturated reactance of the primary, will then further limit, in the worst
case, the half-cycle surge safely within the surge rating of the SSR�
Switching Devices
The power family of semiconductors consists of several switching devices� The
most widely used of this family are metal-oxide semiconductor field-effect transistors
(MOSFETs), silicon controlled rectifiers (SCRs), TRIAC, and Alternistor TRIAC� In
many applications, these devices perform key functions, so you must understand
their advantages as well as their shortcomings to properly design a reliable system�
Applied correctly, SSRs are an asset in meeting environmental, speed, and reliability
specifications which their electromechanical counterparts could not fulfill�
• MOSFET
A power MOSFET is a specific type of metal-oxide semiconductor field-effect transistor
(MOSFET) designed to handle large amounts of power� It is a vertical-structured
transistor capable of sustaining high blocking voltage and high current� Power
MOSFETs are used in DC switching applications� Care must be taken to ensure proper
polarity for all DC ports� Failure to do so can lead to permanent device damage�
• TRIAC
A TRIAC is an electronic component approximately equivalent to two silicon-controlled
rectifiers joined in inverse parallel (paralleled but with the polarity reversed) and with
their gates connected together� This results in a bidirectional electronic switch that can
conduct AC current only� The TRIAC is ideal for switching non-reactive loads�
• Alternistor TRIAC
The Alternistor is specifically designed for applications that switch highly inductive
AC loads� A special chip offers performance similar to two SCRs wired in inverse
parallel (back-to-back), providing better turn-off behavior than a standard TRIAC� The
Alternistor TRIAC is an economical solution, ideal for switching inductive AC loads�
• SCR
The SCR (silicon-controlled rectifier) acts as a switch, conducting when its gate
receives a current pulse, and continuing to conduct as long as it is forward biased�
The SCR is ideal for switching all types of AC loads�
