Product details

What the 1500W rating means on the bench

The 1.5SMC160AHM3/I is a Zener-type TVS diode from Vishay's TransZorb® family, qualified to AEC-Q101 for automotive use. On a 12V or 24V automotive rail, a load-dump or alternator field-decay spike that exceeds the 136V reverse standoff voltage triggers the avalanche breakdown; the diode then clamps the surge to 219V maximum (at 6.8A peak pulse current), protecting downstream electronics.

Fit for automotive and telecom boards

The 152V minimum breakdown voltage and 136V standoff mean this part sits on a rail that normally runs below 136V — a 12V battery bus, a 48V telecom supply, or a 24V industrial line. Operating temperature from -65°C to 150°C covers under-hood ambient and hot-soak conditions.
