The clamping voltage is 207V at a peak pulse current of 7.2A, limiting the let-through energy to a level that protects downstream MOSFETs and ICs rated for 250V or higher. This is a single-channel device (one unidirectional channel), so it protects one rail per package. ## AEC-Q101 qualification and temperature range for underhood duty Qualified to AEC-Q101, the automotive discrete semiconductor stress-test standard, this TVS is rated for operation from -65°C to +150°C junction temperature. That covers the full underhood ambient range — a transmission control unit or engine ECU sees 125°C ambient on a hot day, and the 150°C junction rating provides margin for self-heating during a transient event. ## DO-214AB SMC footprint and board integration Housed in the DO-214AB (SMC) surface-mount package, the device has a standard footprint that reflows on a 0.063-inch thick PCB with typical soldering profiles. The copper pad area under the cathode tab sets the thermal resistance to ambient — a larger pad improves heat dissipation during repetitive transients, though the 1500W rating assumes a single non-repetitive pulse at 25°C. Mounting is surface mount, consistent with automated pick-and-place assembly for automotive ECU and telecom line-card production.","metaTitle":"1.5SMC150AHM3_A/I Vishay TVS, AEC-Q101, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC150AHM3_A/I Zener TVS diode, AEC-Q101 qualified, 1500W peak pulse, 128V standoff, active production, quoted to order.","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, Telecom","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC150","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"143V","Voltage - Clamping (Max) @ Ipp":"207V","Voltage - Reverse Standoff (Typ)":"128V","Current - Peak Pulse (10/1000µs)":"7.2A"}},"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 this part?","answer":"As an AEC-Q101 qualified device, Vishay provides PPAP documentation, RoHS compliance data, and the standard AEC-Q101 qualification report.
