Product details

1500W Zener TVS for automotive 28V rails

The 1.5SMC33AHE3/57T is a 1500W peak pulse power Zener TVS diode from Vishay's TransZorb series, qualified to AEC-Q101 for automotive applications.

AEC-Q101 and the under-hood temperature envelope

AEC-Q101 qualification means this part passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the automotive discrete semiconductor standard. Lifecycle status is Active per the manufacturer — no end-of-life notice, no last-time-buy window.
