BZW04376

® BZW04-5V8/376 BZW04-5V8B/376B TRANSILTM 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.
