The reverse standoff voltage is 23.1V typical, with a breakdown voltage range starting at 25.7V minimum. This means the diode begins conducting at roughly 26V and holds the line below 38V during a surge — a tight clamp for 24V nominal rails in automotive or telecom gear. ## Automotive qualification and deployment context The single unidirectional channel and no power-line protection flag mean this diode is intended for signal or low-side protection, not for clamping the main battery bus. It suits 24V sensor inputs, CAN bus lines, or telecom line-card interfaces where a 23.1V working voltage leaves margin below the 25.7V breakdown threshold. The SMC footprint is standard — the cathode band aligns with the marked end; the tab carries the cathode and sinks heat into the PCB copper pour. Tape and reel packaging suits automated pick-and-place. No special moisture sensitivity level is stated in the record, but the DO-214AB body is molded epoxy — standard MSL 1 handling applies unless a specific bake is called out on the reel label.","metaTitle":"1.5SMC27AHM3/I Vishay TVS, 1500W, 23.1V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC27AHM3/I Zener TVS diode, 1500W peak pulse, 23.1V reverse standoff, AEC-Q101 qualified, DO-214AB SMC package.
