## **BZW04-5V8/376 BZW04-5V8B/376B** ## TRANSIL[TM] ## **FEATURES** - I PEAK PULSE POWER : 400 W (10/1000µs) - I STAND-OFF VOLTAGE RANGE : From 5.8V to 376 V - I UNI AND BIDIRECTIONAL TYPES - I LOW CLAMPING FACTOR - I FAST RESPONSE TIME - I 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. **==> picture [221 x 213] intentionally omitted <==** **----- Start of picture text -----**

**Note :** The curves of the figure 3 are specified for a junction temperature of 25°C before surge. The given results may be extrapolated for other junction temperatures by using the following formula : ∆VBR = αT * (Tamb -25) * VBR (25°C).
