With a 17.1V reverse standoff voltage, this part sits on a 12V or 15V rail and stays out of the way during normal operation. The 19V minimum breakdown voltage means it starts conducting only when the line rises above that threshold, shunting the surge before it reaches downstream silicon. ## Automotive-grade clamping for harsh environments The -65°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles — a 12V ECU input or a sensor power bus sees this temperature band in a hot soak. The DO-214AB (SMC) package is a surface-mount footprint with a large copper tab for heat sinking. On a 2oz copper board with adequate pad area, the junction-to-ambient thermal path handles repetitive pulses as long as the average power stays within the derating curve.","metaTitle":"Vishay 1.5SMC20AHM3_A/I TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC20AHM3_A/I Zener TVS diode, 1500W peak pulse, 17.1V standoff, AEC-Q101 automotive grade.
