1500 W peak pulse — what it means for the board
The 1.5SMC24AHR7G is a Zener-type TVS diode in the 1.5SMC series, rated for 1500 W peak pulse power at 10/1000 µs waveform. That 1500 W rating means it can clamp a 47 A transient pulse down to 33.2 V, protecting downstream silicon from overvoltage events like load dump or inductive kickback. Breakdown starts at 22.8 V minimum, giving a guard band before the clamping region engages.
Automotive grade and AEC-Q101 qualification
This part carries an Automotive grade and is qualified to AEC-Q101, the automotive discrete semiconductor stress-test standard. That means it has passed the full suite of reliability screens — temperature cycling, high-temperature reverse bias, and ESD — for use in under-hood and chassis-domain electronics. The DO-214AB (SMC) package handles the thermal dissipation of a 1500 W pulse without exceeding the junction limit.
Active lifecycle — sourcing for the BOM
It is a single-channel unidirectional device — one TVS per package, cathode band marked.
