The 1.5SMC62CAHM3_A/H: Reverse standoff is 53V nominal, so it sits above the 48V telecom bus or the 12V/24V automotive rail it is protecting, drawing negligible leakage until a transient arrives. When the clamp fires, the maximum clamping voltage is 85V at the rated peak pulse current of 17.6A — the downstream circuitry sees 85V as the ceiling, not whatever the surge delivers.
Automotive and telecom deployment fit
The AEC-Q101 qualification places this part in the automotive quality flow — temperature cycling, humidity, and mechanical stress screens that consumer-grade TVS diodes skip. Package is DO-214AB (SMC) on tape and reel — the standard footprint for 1.5 kW TVS diodes, compatible with any SMT line set up for SMC pick-and-place and reflow.
