Vishay has marked the 1.5SMC540A-/9AT as obsolete. No pin-compatible successor is listed in the official record. For existing BOM lines that require this specific TVS, independent distribution and surplus inventory are the available supply paths. Each lot is sourced with traceability; counterfeit screening and date-code verification are part of the procurement process. The DO-214AB (SMC) package uses the standard JEDEC footprint for this body size — the same land pattern as the SMCJ suffix. The cathode band marks the unidirectional orientation.","metaTitle":"1.5SMC540A-E3/9AT Vishay Zener TVS, 1.5kW, DO-214AB","metaDescription":"Obsolete Vishay 1.5SMC540A-E3/9AT Zener TVS diode, 1500W peak pulse, 459V standoff, DO-214AB.
