With a 1500 W peak pulse power rating at the 10/1000 µs wave shape, it absorbs transients that would exceed the working voltage of downstream circuitry on low-voltage rails. The reverse standoff voltage of 7.02 V typ is the working voltage the protected rail sits at during normal operation; the clamping voltage of 12.1 V max at the rated peak pulse current of 124 A is the ceiling the diode enforces when a transient fires. The minimum breakdown of 7.79 V sits between the two, giving the diode enough headroom above nominal to stay off during normal operation. ## Peak pulse rating — what 124 A means in the field Peak pulse current of 124 A at 10/1000 µs sets the fault energy the diode can survive before the clamping voltage climbs beyond the 12.1 V ceiling. A 1500 W rating at that wave shape is the product of the clamping voltage and the peak current — the diode dissipates the transient energy in roughly a millisecond window, so the 124 A figure is not a continuous current rating; it is a single-event survivability number. The clamping voltage of 12.1 V max means the protected node is held below 12.1 V even as the transient current reaches 124 A — the dynamic resistance of the Zener avalanche determines how much the clamping voltage climbs as current rises. For a 5 V rail with ±10% tolerance, 12.1 V sits above the 5.5 V absolute-maximum of most ICs but within the transient-withstand window of well-designed downstream stages. ## Automotive qualification and sourcing posture The AEC-Q101 qualification confirms this part has passed the automotive stress tests — temperature cycling, high-temperature reverse bias, and pulsed operation — required to be used in automotive modules without additional screening. The wide junction temperature range of -65 °C to 150 °C covers both cold-start and engine-compartment ambient conditions. The part is listed as Active in production. It ships on tape and reel per the supplier device package designation DO-214AB (SMCJ). Availability and lead time confirmed at RFQ through independent distribution channels carrying this Vishay General Semiconductor part.","metaTitle":"Vishay 1.5SMC8.2AHE3/9AT TVS Diode, 7.02V Standoff","metaDescription":"Vishay 1.5SMC8.2AHE3/9AT unidirectional TVS diode, 1500W peak pulse, 7.02V standoff, 12.1V clamping, AEC-Q101, DO-214AB SMC, active.","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":"1.5SMC8.2","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5SMC8.2AHE3/9AT's peak pulse clamping voltage and what does it protect?","answer":"The maximum clamping voltage is 12.1 V at the rated peak pulse current of 124 A.
