The breakdown voltage range starts at 10.5V, so the device begins clamping just above the normal rail voltage, leaving the protected circuitry a margin before the clamp fires. ## Package and board integration Housed in the DO-214AB (SMC) surface-mount package, the same footprint as the SMCJ suffix devices. The package is standard for 1500W TVS diodes — the large tab area on the cathode side conducts the surge heat into the PCB copper, so the board layout's thermal pad area directly affects how many pulses the part can absorb before the junction hits 150°C. Supplied on tape and reel (the /57T suffix) or cut tape, the part is pick-and-place ready. ## Lifecycle and supply position Sourced through independent distribution channels. No pin-compatible second-source is listed on the Vishay cross-reference, but the 1.5SMC family is widely second-sourced by other TVS diode manufacturers — a parametric search for 1500W, 9.4V standoff, DO-214AB will turn up alternatives if a second source is needed.","metaTitle":"1.5SMC11A-E3/57T Vishay TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC11A-E3/57T Zener TVS diode, 1500W peak pulse power, 9.4V standoff, 15.6V clamp.
