Standoff voltage sits at 64.1 V typical, with a minimum breakdown of 71.3 V and a clamping maximum of 104 V at the 14.6 A peak-pulse current (10/1000 µs waveform). That 104 V ceiling is the number that sizes the clamping Schottky or MOSFET on the protected side — the diode itself absorbs the transient energy and clamps the rail before the downstream IC sees overvoltage. Peak pulse power is 1500 W (1.5 kW) — this is the short-duration rating for the 10/1000 µs surge profile; the 1.5SMC series is Vishay's mid-power SMC-body TVS family sitting above the 1.5KE series in surge current capability. ## AEC-Q101 grade and the -65 to 150 °C junction window AEC-Q101 qualification means this part has passed the automotive stress sequence (temperature cycling, high-temperature reverse bias, humidity life) and is eligible for PPAP submission — it is a legitimate automotive-grade TVS, not a commercial-grade part with a datasheet description. The part ships on tape & reel — confirm the pick-and-place feeder width and the vacuum nozzle landing pad diameter against the DO-214AB body outline before committing a high-speed placement line; the SMC body is wider than a SOT-23 and needs adequate standoff clearance on the reel pocket. ## Where 1.5SMC TVS diodes protect Primary applications listed are automotive and telecom — the 64 V standoff puts this squarely on 48 V automotive mild-hybrid bus protection, traditional 12 V distribution rails with 24 V transients during load dump, and telecom DC power feeds where mains disturbances couple into the rail. The TransZorb® trade name denotes Vishay's isolated-junction construction — it behaves like a conventional Zener in steady state and switches to avalanche clamping during the surge event, returning to the off state once the transient clears without degradation.","metaTitle":"1.5SMC75CAHM3_A/H TVS Diode 1500W 71.3V DO-214AB","metaDescription":"Vishay 1.5SMC75CAHM3_A/H bidirectional TVS diode, 1500W peak pulse, 64.1V standoff, 104V clamping, AEC-Q101 qualified, DO-214AB SMC.
