TRANSIL^TM

FEATURES

PEAK PULSE POWER : 5000 W (10/1000µs)

STAND-OFF VOLTAGERANGE :

From 10V to 180V

UNI AND BIDIRECTIONAL TYPES

LOW CLAMPING FACTOR

FAST RESPONSE TIME

UL RECOGNIZED

DESCRIPTION

Transil diodes provide high overvoltage protection

by clamping action. Their instantaneous response

to transient overvoltages makes them particularly

suited to protect voltage sensitive devices such

as MOS Technology and low voltage supplied

IC’s.

Note : The curves of the figure 3 are specified for a junction temperatureof 25 °C before surge.

The given results may be extrapolatedfor other junction temperaturesby usingthe following formula :

∆V_BR= αT _*(T_amb-25) _*V_BR(25°C).

For intermediatevoltages, extrapolate the givenresults.
