Product details

The 1.5SMC33AHM3/H is a 1500 W peak pulse power Zener TVS diode from Vishay's 1.5SMC series, qualified to AEC-Q101 for automotive applications.

AEC-Q101 qualification and the automotive temperature band

AEC-Q101 qualification means this part has passed the reliability stress tests (HTRB, H3TRB, temperature cycling, ESD) required for automotive-grade discrete semiconductors.

Frequently asked questions

What applications is the 1.5SMC33AHM3/H suited for?

It is designed for automotive and telecom applications where a 1500 W peak pulse power TVS is needed on a 24 V nominal rail. The AEC-Q101 qualification makes it suitable for under-hood and engine-bay transient protection.
