Product details

Surge rating and automotive qualification

The 1.5SMC22CAHE3/57T is a 1500W peak pulse power TVS diode in the TransZorb series, rated for 10/1000 µs waveform. With a clamping voltage of 30.6V at 49A peak pulse current, it shunts transients on 18.8V nominal DC rails — typical for 24V automotive systems where load-dump and alternator field decay can exceed the battery voltage.

Package and mounting

Housed in a DO-214AB (SMC) package, the same footprint as the SMCJ industry standard. Supplied in Tape & Reel — the /57T suffix indicates the 13-inch reel quantity. No power line protection confirms this is a pure transient suppressor, not a crowbar or ESD-only device.

Marked as Active — Vishay continues to manufacture this part.
