Clamping window and peak pulse rating
The 1.5SMC43CAHE3/57T: Rated for 1500 W peak pulse power (1.5 kW) under the standard 10/1000 µs test condition, the device absorbs high-energy transients like load-dump or inductive kickback without failing short.
Automotive qualification and temperature range
AEC-Q101 qualified and intended for automotive applications, this TVS is screened for the reliability stresses typical of under-hood and chassis-mounted electronics — temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive grade standard.
Supplied on tape and reel (TR), the 1.5SMC43CAHE3/57T is compatible with standard pick-and-place and reflow soldering profiles. No power line protection feature is claimed — this is a dedicated transient suppressor, not a crowbar or overvoltage protector for continuous DC rails.
