BZW50
Transil™, transient voltage surge suppressor (TVS)
Datasheet production data
Features
■ Peak pulse power: 5000 W (10/1000 µs)
■ Stand-off voltage range from 10 V to 180 V
■ Unidirectional and bidirectional types
■ Low clamping factor
■ Fast response time
■ 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.
