This is a unidirectional Zener-type suppressor — one channel, cathode band marked on the DO-214AB body. No power line protection flag means it is intended for signal or low-voltage DC bus protection, not mains AC clamping. ## Package and board-fit for field replacement Housed in the standard DO-214AB (SMC) package, the same footprint as the SMCJ series. The body is large enough to hand-solder with a standard iron — no hot-air station required for a field swap. Polarity is marked with a cathode band on the body; the anode side is the tab. On a single-sided board, the tab pad should get a generous copper pour to sink the 1500 W pulse heat into the board.","metaTitle":"Littelfuse 1.5SMC350A TVS Diode, 300V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC350A Zener TVS diode, 1500W peak pulse power, 300V reverse standoff, 482V clamping.
