## **BZW04-5V8/376 BZW04-5V8B/376B** 

## TRANSIL[TM] 

## **FEATURES** 

- PEAK PULSE POWER : 400 W (10/1000µs) STAND-OFF VOLTAGERANGE : From 5.8V to 376 V 

- 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 : ∆VBR = αT * (Tamb -25) * VBR (25°C). For intermediatevoltages, extrapolate the givenresults.
