At 1500 W peak pulse power rating, this part handles the standard 1.5 kW surge class — common in AC-line protection, bus-clamp, and motor-drive environments where lightning-induced transients or inductive kickback exceed what a downstream regulator can absorb. The 150 °C junction temperature ceiling gives thermal headroom in enclosed panels without active cooling. ## Who is still building boards with the 1.5SMC8.2A series The TransZorb® construction (Vishay's internal glass-junction passivation) gives it better surge-survival than a plain Zener clamp in repetitive transient environments.","metaTitle":"1.5SMC8.2A-M3/9AT TVS Diode, 7.02V Standoff, 12.1V Clamp","metaDescription":"Vishay 1.5SMC8.2A-M3/9AT unidirectional TVS diode, 7.02V standoff, 12.1V clamping at 124A peak pulse, 1500W peak power, -65 to 150°C junction.","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":"1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC8.2","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)":"7.79V","Voltage - Clamping (Max) @ Ipp":"12.1V","Voltage - Reverse Standoff (Typ)":"7.02V","Current - Peak Pulse (10/1000µs)":"124A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3333","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What voltage does this TVS actually clamp at under surge?","answer":"Maximum clamping voltage is 12.1 V at the rated peak pulse current of 124 A (10/1000 µs).
