Mounting is standard reflow; the tape-and-reel packaging (Cut Tape also available) suits pick-and-place for production runs. For a 24V DC bus, the 23.1V standoff provides margin against nominal rail variations while still triggering before the downstream silicon sees damaging overvoltage. The 1.5SMC series is a standard Zener TVS family with broad second-source coverage, so single-source risk is low.","metaTitle":"1.5SMC27A Littelfuse TVS Diode, 1500W, 23.1V Standoff","metaDescription":"Littelfuse 1.5SMC27A Zener TVS diode, 1500W peak pulse, 23.1V standoff, 37.5V clamping, DO-214AB.
