BZW50-39B
BZW50
Datasheet
5 kW TVS
Features
• Peak pulse power:
– 5000 W (10/1000 µs)
• Stand off voltage range from 10 V to 180 V
• Unidirectional and bidirectional diode
• Low clamping factor
R6 • 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.
