Clamping voltage and peak pulse rating
The 1.5SMC8.2AHM6G: The minimum breakdown voltage is 7.79 V — transients above this level fire the clamping path and hold the protected rail at the clamping ceiling. Maximum clamping voltage at the 130 A peak pulse current is 12.1 V; that 12.1 V is what the downstream circuit sees during a surge event — the TVS absorbs the energy and clamps the spike before it reaches the load.
AEC-Q101 automotive grade and thermal margin
AEC-Q101 qualification means this part passed the automotive discrete stress sequence: temperature cycling, high-temperature reverse bias, power temperature cycling, and humidity combined with temperature and bias — relevant if you are writing PPAP documentation or a safety-case for an ECU module.
Package and sourcing posture
DO-214AB (SMC) is the industry-standard 2-pin surface-mount package for 1.5–3 kW TVS diodes — the anode and cathode pad geometry on the datasheet footprint determines the thermal impedance, not the housing itself. Tape-and-reel packaging at 7-inch or 13-inch reel standard — confirm reel size and quantity per reel against your pick-and-place feeder before committing a BOM quantity.
