Product details

1.5 kW Zener TVS for 40 V automotive rails

The Vishay 1.5KE47AHE3_A/C is a 1500 W peak-pulse Zener TVS diode in the TransZorb Automotive series, designed to clamp transients on 40.2 V reverse-standoff rails in automotive and industrial power systems. A single unidirectional channel provides a breakdown voltage of 44.7 V minimum and a clamping voltage of 64.8 V maximum at the 23.1 A peak pulse current (10/1000 µs waveform).

AEC-Q101 and 175 °C junction rating

Qualified to AEC-Q101, this part is stress-tested for automotive reliability — the -55 °C to +175 °C operating junction range covers under-hood ambient temperatures with margin for self-heating during a pulse.
