1500W peak pulse — the protection envelope
The 1.5SMC100AHM3_A/H: The 85.5 V reverse standoff voltage means the diode stays out of the circuit under normal operating conditions, only conducting when the line exceeds that threshold. Breakdown occurs at a minimum of 95 V, giving a 9.5 V guard band between the standoff and the clamping knee — enough margin for 85 V nominal rails with ripple.
AEC-Q101 Grade — automotive and telecom deployment
Qualified to AEC-Q101, the automotive-grade discrete semiconductor standard, this TVS is stress-tested for under-hood and chassis electronics where temperature swings and transients are severe. The -65°C to 150°C junction temperature range covers cold-crank and hot-soak conditions in engine-bay or transmission-control modules. Listed applications include Automotive and Telecom — the 1500 W pulse rating suits it for 12 V and 24 V vehicle systems as well as 48 V telecom rectifier outputs.
DO-214AB SMC — surface-mount board fit
Housed in the DO-214AB (SMC) package, the same footprint as the standard 1.5SMC series, so existing PCB layouts for the 1.5SMC100A variant accept this automotive-grade version without a board spin. Supplied on Tape & Reel, compatible with automated pick-and-place assembly lines.
