Product details

The Vishay 1.5SMC120AHE3/57T is a 1500 W (1.5 kW) peak pulse power Zener TVS diode from the automotive-grade 1.5SMC series, built on the TransZorb® technology.

Automotive transient protection with AEC-Q101 qualification

The single unidirectional channel is the standard configuration for DC rail clamping in automotive ECUs, battery management systems, and sensor modules.

Active lifecycle — no end-of-life pressure

The Tape & Reel packaging (7-inch reel, standard quantity) suits automated pick-and-place assembly for volume production.
