The -65°C to 150°C junction temperature range covers underhood and engine-adjacent deployments where ambient peaks exceed 125°C. ## Clamping voltage and pulse current that define the protection margin At the 10/1000 µs test waveform, the 16.7 V clamping voltage (max) at 89.8 A peak pulse current gives the design team a clear voltage ceiling to size the downstream DC-DC converter or load switch. The 11.4 V minimum breakdown ensures the TVS does not conduct at 12 V steady-state, but triggers before the rail exceeds the typical 28 V load-dump clamp. The 10.2 V standoff is the working voltage where leakage stays negligible.","metaTitle":"1.5SMC12AHM3/H Vishay TVS, 1500W, 10.2V Standoff, AEC-Q101","metaDescription":"Vishay 1.5SMC12AHM3/H Zener TVS diode, 1500W peak pulse, 10.2V standoff, 16.7V clamp, AEC-Q101 qualified, DO-214AB.
