The DO-214AB (SMC) package is surface-mount, with a low-inductance footprint that preserves the fast response time inherent to Zener avalanche breakdown. ## Active production, single-source BOM line For a BOM line that cannot tolerate a single-supplier exposure, qualifying an alternate TVS from a different family with the same 12.8 V standoff and DO-214AB footprint is a prudent hedge.","metaTitle":"Littelfuse 1.5SMC15A TVS Diode, 1500W, 12.8V Standoff","metaDescription":"Littelfuse 1.5SMC15A Zener TVS diode, 1500W peak pulse power, 12.8V reverse standoff, DO-214AB.
