NPMC Series

Ultra Low Capacitance

TSPD

The NPMC series of Low Capacitance Thyristor Surge Protection

Devices (TSPD) protect sensitive electronic equipment from transient

overvoltage conditions. Due to their ultra low off−state capacitance

(Co), they offer minimal signal distortion for high speed equipment

such as DSL and T1/E1 circuits. The low nominal offstate capacitance

translates into the extremely low differential capacitance offering

superb linearity with applied voltage or frequency.

The NPMC Series helps designers to comply with the various

regulatory standards and recommendations including:

GR−1089−CORE, IEC 61000−4−5, ITU K.20/K.21/K.45, IEC 60950,

TIA−968−A, FCC Part 68, EN 60950, UL 1950.

Detailed Operating Description

The TSPD or Thyristor Surge Protection Device are

specialized silicon based overvoltage protectors, used to

protect sensitive electronic circuits from damaging

overvoltage transient surges caused by induced lightning

and powercross conditions.

The TSPD protects by switching to a low on state voltage

when the specified protection voltage is exceeded. This is

known as a “crowbar” effect. When an overvoltage occurs,

the crowbar device changes from a high−impedance to a

low−impedance state. This low−impedance state then offers

a path to ground, shunting unwanted surges away from the

sensitive circuits.

This crowbar action defines the TSPD’s two states of

functionality: Open Circuit and Short Circuit.

Open Circuit – The TSPD must remain transparent during

normal circuit operation. The device looks like an open

across the two wire line.

Short Circuit – When a transient surge fault exceeds the

TSPD protection voltage threshold, the devices switches on,

and shorts the transient to ground, safely protecting the

circuit.

Operation during a Fault

I(Fault)

•TSPD looks like an open

•Circuit operates normally

•Fault voltage greater than Vbo occurs

•TSPD shorts fault to ground

•After short duration events the O/V

switches back to an open condition

•Worst case (Fail/Safe)

•O/V permanent short

•Equipment protected

The electrical characteristics of the TSPD help the user to

define the protection threshold for the circuit. During the

open circuit condition the device must remain transparent;

this is defined by the IDRM. The IDRM should be as low as

possible. The typical value is less than 5 mA.

The circuit operating voltage and protection voltage must

be understood and considered during circuit design. The

V(BO) is the guaranteed maximum voltage that the protected

circuit will see, this is also known as the protection voltage.

The VDRM is the guaranteed maximum voltage that will

keep the TSPD in its normal open circuit state. The TSPD

V(BO) is typically a 20−30% higher than the VDRM. Based

on these characteristics it is critical to choose devices which

have a VDRM higher than the normal circuit operating

voltage, and a V(BO) which is less than the failure threshold

of the protected equipment circuit. A low on−state voltage

Vt allows the TSPD to conduct large amounts of surge

current (500 A) in a small package size.

Once a transient surge has passed and the operating

voltage and currents have dropped to their normal level the

TSPD changes back to its open circuit state.

TSPD’s are useful in helping designers meet safety and

regulatory standards in Telecom equipment including

GR−1089−CORE, ITU−K.20, ITU−K.21, ITU−K.45, FCC

Part 68, UL1950, and EN 60950.

ON Semiconductor offers a full range of these products in

the NP series product line.

DEVICE SELECTION

When selecting a TSPD use the following key selection

parameters.

Off−State Voltage VDRM

Choose a TSPD that has an Off−State Voltage greater than

the normal system operating voltage. The protector should

not operate under these conditions:

Example:

Vbat = 48 Vmax

Vring = 150 Vrms = 150*1.414 = 212 V peak

VDRM should be greater than the peak value of these two

components:

VDRM > 212 + 48 = 260 VDRM

Breakover Voltage V(BO)

Verify that the TSPD Breakover Voltage is a value less

than the peak voltage rating of the circuit it is protecting.

Example: Relay breakdown voltage, SLIC maximum

voltage, or coupling capacitor maximum rated voltage.

Peak Pulse Current Ipps

Choose a Peak Pulse current value which will exceed the

anticipated surge currents in testing. In some cases the 100 A

“C” series device may be needed when little or no series

resistance is used. When a series current limiter is used in the

circuit a lower current level of “A” or “B” may be used. To

determine the peak current divide the maximum surge

current by the series resistance.

Hold Current (IH)

The Hold Current must be greater than the maximum

system generated current. If it is not then the TSPD will

remain in a shorted condition, even after a transient event

has passed.
