For a BOM already qualified to this DO-214AB footprint and 300V standoff, the 1.5SMC350 remains a functional drop-in if stock is found. Confirm the exact breakdown voltage window and clamping performance against the existing design's surge requirements before committing.","metaTitle":"1.5SMC350 Littelfuse TVS Diode, 300V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC350 Zener TVS diode, 1500W peak pulse, 300V reverse standoff, 506.1V clamping.
