ASSR-3210, ASSR-3211, ASSR-3220
General Purpose, Form A, Solid State Relay (Photo MOSFET)
(250V/0.2A/10)
Data Sheet
Description
The ASSR-32XX Series consists of an AlGaAs infrared
light-emitting diode (LED) input stage optically coupled
to a high-voltage output detector circuit. The detector
consists of a high-speed photovoltaic diode array and
driver circuitry to switch on/o two discrete high volt-
age MOSFETs. The relay turns on (contact closes) with a
minimum input current of 3mA through the input LED.
The relay turns o (contact opens) with an input voltage
of 0.8V or less.
The single channel con gurations, ASSR-3210 and ASSR-
3211, are equivalent to 1 Form A Electromechanical
Relays (EMR), and the dual channel con guration, ASSR-
3220, is equivalent to 2 Form A EMR. They are available
in 4-pin SO, 6-pin DIP, 8-pin DIP and Gull Wing Surface
Mount for DIP packages. Their electrical and switching
characteristics are speci ed over the temperature range
of -40°C to +85°C. They are used for general purpose
switching of signals and low power AC/DC loads.
ASSR-3211 enables AC/DC and DC-only output connec-
tions. For DC-only connection, the output current, Io,
increases to 0.4A and the on-resistance, R(ON) reduces
to 2.5.

Notes:
1. For derating, refer to Figure 1 and 2.
2. The voltage across the output terminals of the relay should not exceed this rated withstand voltage. Over-voltage protection circuits should be
added in some applications to protect against over-voltage transients.”
3. Threshold to switch device is IF 0.5mA, however, for quali ed device performance over temperature range, it is recommended to operate at
IF =5mA. Refer to application information in next section of this datasheet.
4. Device is considered as a two terminal device:
ASSR-3210 - pin 1, 2 shorted and pin 3, 4 shorted.
ASSR-3211 - pin 1, 2, 3 shorted and pin 4, 5, 6 shorted.
ASSR-3220 - pin 1, 2, 3, 4 shorted and pin 5, 6, 7, 8 shorted.
5. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous
voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if applicable), your
equipment level safety speci cation, or Avago Technologies Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”
6. During the pulsed R(ON) measurement ( IO duration 30ms), ambient (TA) and case temperature (TC) are equal.
Applications Information
On-Resistance and Derating Curves
The Output On-Resistance, R(ON), speci ed in this data
sheet, is the resistance measured across the output
contact when a pulsed current signal (Io=0.2A) is ap-
plied to the output pins. The use of a pulsed signal (≤
30ms) implies that each junction temperature is equal
to the ambient and case temperatures. The steady-state
resistance, Rss, on the other hand, is the value of the re-
sistance measured across the output contact when a DC
current signal is applied to the output pins for a duration
su cient to reach thermal equilibrium. Rss includes the
e ects of the temperature rise in the device.
Derating curves are shown in Figures 1 and 2, specify ing
the maximum output current allowable for a given am-
bient temperature. The maximum allowable output cur-
rent and power dissipation are related by the ex pression
Rss=Po(max)/(Io(max))2 from which Rss can be calculated.
Staying within the safe area assures that the steady state
MOSFET junction temperature remains less than 125°C.
Turn On Time and Turn O Time Variation
The ASSR-32XX Series exhibits a very fast turn on and
turn o time. Both the turn on and turn o time can be
adjusted by choosing proper forward current as depicted
in Figures 9 and 11. The changes of the turn on and turn
o time with ambient temperature are also shown in
Figures 10 and 12.
