The single unidirectional channel handles positive-going surges; for bidirectional protection on an AC or bipolar rail, a pair back-to-back is needed. ## Temperature range and soldering reality The DO-214AB (SMC) footprint is standard — the cathode band and package outline match the industry-standard SMCJ land pattern, so the PCB layout is interchangeable with other 1.5SMC-series parts.","metaTitle":"Littelfuse 1.5SMC56A TVS Diode, 1500W, 77V Clamp","metaDescription":"Littelfuse 1.5SMC56A Zener TVS, 1500W peak pulse, 77V clamping, 47.8V standoff.
