The 165 V clamp at 9.1 A peak pulse current (10/1000 µs) defines the maximum voltage a downstream IC sees during a surge — a 24 V ECU with a 60 V abs-max rail has ample headroom. Operating temperature spans -65°C to 150°C junction, covering cold-crank and engine-bay heat soak conditions where the ambient can exceed 125°C.","metaTitle":"1.5SMC120AHE3_A/H Vishay TVS, 1500W, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC120AHE3_A/H Zener TVS, 1500W peak pulse, 102V standoff, 165V clamp.
