No power line protection (the part is unidirectional, not a steering diode array), so it is a single-event clamp, not a rail-to-rail ESD protector. The base product number 1.5SMC30 covers the full family, so the suffix AHM3/H identifies the AEC-Q101 qualified, halogen-free variant in tape-and-reel packaging.","metaTitle":"1.5SMC30AHM3/H Vishay TVS, 1.5kW, 25.6V Standoff","metaDescription":"Vishay 1.5SMC30AHM3/H Zener TVS, 1500W peak pulse, 25.6V reverse standoff, AEC-Q101 qualified.
