For existing BOM lines, sourcing is through independent distribution channels where remaining stock or surplus lots are quoted per RFQ. ## Board-fit and procurement reality The DO-214AB (SMC) package is a standard JEDEC footprint — the same land pattern serves many 1.5SMC-series TVS diodes, so a board spin is not needed if the replacement shares the same package and pinout.","metaTitle":"1.5SMC15AT3G Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC15AT3G Zener TVS, 1500W peak pulse, 12.8V standoff, 21.2V clamp.
