It is a unidirectional device with a single protection channel, suited for DC power bus clamping in engine control units, body controllers, and telecom line cards. ## Clamping profile and board-fit decisions The 12.8V reverse standoff voltage sits just above a nominal 12V battery rail, so the diode does not conduct during normal operation. Breakdown triggers at 14.3V min, and the clamp holds at 21.2V max — this window ensures the protected circuit sees no more than 21.2V during a surge event. No power line protection (the device is unidirectional, not a steering diode array), so it is used across a single DC rail rather than on data lines. The DO-214AB (SMC) package is a standard surface-mount footprint, reflow-compatible with typical lead-free profiles. ## Lifecycle and supply posture The base product number 1.5SMC15 covers the voltage variant family; the full suffix (HM3_A/H) encodes the AEC-Q101 automotive grade and packaging.","metaTitle":"1.5SMC15AHM3_A/H Vishay TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC15AHM3_A/H Zener TVS diode, 1500W peak pulse, 12.8V standoff, AEC-Q101 qualified.
