It is a single unidirectional channel, so it clamps only one polarity — use it on positive DC rails with the cathode to the protected line. The DO-214AB footprint is shared by many TVS diodes in the 1500W class, making board-level replacement straightforward if a different voltage rating is needed later. The part is classified for General Purpose applications, which covers industrial, telecom, and consumer equipment. RoHS compliance is standard for the series, though the exact certification status should be confirmed against the manufacturer's documentation at order time.","metaTitle":"Littelfuse 1.5SMC220A TVS Diode, 1500W, 185V Standoff","metaDescription":"Littelfuse 1.5SMC220A Zener TVS diode, 1500W peak pulse power, 185V reverse standoff, 328V clamping.
