For existing designs already qualified on this Vishay part number, the surplus and independent-distribution channel is the practical sourcing path. Availability and pricing are lot-specific and confirmed at RFQ — no blanket stock claim. ## DO-214AB footprint — layout note The part ships in a DO-214AB (SMC) package, also referred to as SMCJ in supplier device codes.","metaTitle":"1.5SMC400A-E3/9AT Vishay TVS, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC400A-E3/9AT Zener TVS, 1500W peak pulse, 342V standoff, DO-214AB.
