The clamping voltage at that current is 16.7V max, keeping downstream electronics within a safe voltage during load-dump or inductive kickback events. ## Breakdown and clamping window Minimum breakdown voltage is 11.4V, ensuring the device starts conducting before the protected rail exceeds the safe operating area of typical 12V-rated ICs. The 10.2V standoff voltage means continuous DC bias up to that level draws negligible leakage current. Operating temperature range spans -65°C to 150°C junction, covering under-hood automotive ambient and cold-crank conditions. The DO-214AB (SMC) surface-mount package handles the 1.5kW pulse without exceeding the package thermal limits when mounted with adequate PCB copper.","metaTitle":"1.5SMC12AHM3_A/I Vishay TVS, 1.5kW, 10.2V Standoff","metaDescription":"Vishay 1.5SMC12AHM3_A/I Zener TVS diode, 1500W peak pulse, 10.2V reverse standoff, AEC-Q101, DO-214AB.
