The single unidirectional channel and the absence of power line protection confirm this is a signal-rail or low-side clamp, not a direct AC mains protector. The base product number 1.5SMC56 covers multiple package and qualification variants; the AHM3_A/I suffix specifically denotes the AEC-Q101 qualified version in Tape & Reel packaging, which is the ordering code for automotive production lines.","metaTitle":"1.5SMC56AHM3_A/I Vishay TVS Zener, 1.5kW, AEC-Q101","metaDescription":"Vishay 1.5SMC56AHM3_A/I automotive TVS Zener, 1500W peak pulse, 47.8V standoff, DO-214AB.
