Supplied in Tape & Reel (TR) format, it is suited for volume production runs where the reel quantity matches the BOM line consumption. No pin-compatible direct replacement is listed by Littelfuse, so a BOM review for an alternative TVS with equivalent 300 V standoff and 1500 W rating in DO-214AB is advised for new designs. The part carries no power line protection rating (No per), confirming it is intended for secondary-side DC rail or signal line clamping, not AC mains primary protection.","metaTitle":"1.5SMC350C Littelfuse TVS, 1500W, 300V, DO-214AB","metaDescription":"Littelfuse 1.5SMC350C bidirectional Zener TVS, 1500W peak pulse, 300V reverse standoff, DO-214AB.
