BZW50-10,B/180,B TRANSILTM 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 AG 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.
