FEATURES

PEAK PULSE POWER : 5000 W (10/1000ms)

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 1 : For a surge greater than the maximum values, the diode will fail in short-circuit.

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

The given results may be extrapolatedfor other junction temperaturesby using the following formula : DVBR = aT * (Tamb -25) * VBR (25°C).

For intermediate voltages, extrapolate the given results.
