It clamps at 25.2 V maximum with a 59.5 A peak pulse current (10/1000 µs waveform), protecting a 15.3 V reverse standoff rail — the typical 12 V battery or 15 V supply in an engine bay or telecom line card. ## Clamping voltage and breakdown margin Minimum breakdown voltage is 17.1 V, giving a 1.8 V guard band above the 15.3 V standoff — enough headroom to avoid nuisance triggering from normal ripple on a 12 V system. Maximum clamp at 25.2 V keeps the protected IC below its absolute-max rating in most 24 V-tolerant designs. Operating junction temperature spans -65°C to 150°C, covering under-hood hot-soak and cold-crank conditions without derating the pulse capability.","metaTitle":"1.5SMC18AHM3_A/I TVS Diode, 1500W, 15.3V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC18AHM3_A/I Zener TVS, 1500W peak pulse, 15.3V reverse standoff, AEC-Q101 qualified.
