Product details

1500W surge protection for 12V automotive rails

The 1.5SMC12H is a 1500W peak pulse power Zener TVS diode in the standard DO-214AB (SMC) surface-mount package, designed to clamp transients on 12V nominal automotive power buses.

AEC-Q101 qualification and temperature range

The 1500W peak pulse rating at 25°C derates linearly above that temperature; at 150°C the derated capability is approximately 600W, still sufficient for most automotive transient events on a 12V bus.
