This is a unidirectional device (one channel), so it protects a single line against positive-going transients relative to ground. ## DO-214AB (SMC) footprint and temp range Packaged in the standard DO-214AB (SMC) surface-mount case, the 1.5SMC20A fits the same footprint as the SMCJ family. Available in Tape & Reel (TR) for high-volume pick-and-place, or Cut Tape (CT) for prototyping and small-batch builds. No power line protection feature is claimed — this is a general-purpose transient suppressor, not a specialized rail clamp for DC power buses.","metaTitle":"1.5SMC20A Littelfuse TVS Diode, 1500W, 17.1V Standoff","metaDescription":"Littelfuse 1.5SMC20A Zener TVS, 1500W peak pulse power, 27.7V clamping, 54.9A Ipp, DO-214AB.
