Surface Mount Transient Voltage Suppressors
SM8Z Series 10 To 43 V 6600W
Description
The SM8Z series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by lightning
and other transient voltage events.
Working Voltage: 10 to 43 V
Peak Pulse Power: 6600 W
Features
Glass passivated chip
6600 W peak pulse power capability with a
10/1000 us waveform, repetitive rate (duty
cycle):0.01 %
T J = 175 °C capability suitable for high reliability
and automotive requirement
Meets ISO7637-2 surge specification (varied by test
condition)Meet AEC-Q101 requirement
Low leakage
Uni-directional polarity
Excellent clamping capability
Very fast response time
RoHS compliant
Applications
Use in sensitive electronics protection against voltage transients
induced by inductive load switching and lighting, especially for
automotive load dump protection application
