The -65°C to 150°C junction temperature range covers under-hood thermal extremes. ## DO-214AB SMC package and board integration Housed in a DO-214AB (SMC) surface-mount package, the device footprint matches the industry-standard SMCJ outline. The large copper tab on the cathode side conducts heat to the PCB copper plane — the junction-to-ambient thermal resistance depends on the pad area, so a 1-inch² copper land is recommended for full 1500W pulse capability. The base product number is 1.5SMC15, so the same die is available in other package or lead-free variants under that base.","metaTitle":"1.5SMC15AHE3/57T Vishay TVS, 1500W, 12.8V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC15AHE3/57T Zener TVS diode, 1500W peak pulse, 12.8V reverse standoff, AEC-Q101 qualified, DO-214AB SMC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC15","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.3V","Voltage - Clamping (Max) @ Ipp":"21.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"70.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Vishay provide for 1.5SMC15AHE3/57T?","answer":"As an AEC-Q101 qualified device, Vishay provides automotive-grade PPAP documentation, RoHS compliance data, and a full datasheet with electrical characteristics and thermal derating curves.
