Product details

1500W Zener TVS — what the ratings mean for the BOM

The 1.5KE16AHE3/51 is a 1500W peak-pulse-power Zener TVS diode from Vishay's TransZorb® automotive series, AEC-Q101 qualified. Its 13.6V reverse standoff voltage means it sits across a 12V nominal rail and stays transparent until a transient exceeds that threshold. When it triggers, the clamping voltage is held to 22.5V at the full 66.7A peak pulse current (10/1000µs waveform) — this is the protection ceiling the downstream components must survive.

Obsolete — sourcing reality for the 1.5KE16AHE3/51

A pin-compatible alternative from the same series with the same package and voltage class may exist — confirm the exact breakdown and clamping tolerances against the 15.2V min breakdown and 22.5V max clamp before substituting.
