BZW50-150 STMicroelectronics

BZW50 Datasheet 5 kW TVS Features Peak pulse power: 5000 W (10/1000 s) Stand off voltage range from 10 V to 180 V Unidirectional and bidirectional diode Low clamping factor Fast response time R6 UL497B, file number: QVGQ2.E136224 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 ICs.
