The 1500 W peak pulse rating (10/1000 µs) is the energy-handling floor for load-dump or inductive kickback events in an engine-bay environment. No power-line protection (the device is unidirectional, single-channel) — it protects one rail per package, typical for point-of-load clamping on sensor or actuator power feeds.","metaTitle":"1.5KE82HE3/73 Vishay TVS, 1500W, 66.4V Standoff, AEC-Q101","metaDescription":"1.5KE82HE3/73 is obsolete; a 1500W unidirectional TVS Zener, AEC-Q101 qualified, 66.4V standoff, 118V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, TransZorb®","Package":"Tape & Box (TB)","Applications":"Automotive","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE82","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"73.8V","Voltage - Clamping (Max) @ Ipp":"118V","Voltage - Reverse Standoff (Typ)":"66.4V","Current - Peak Pulse (10/1000µs)":"12.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE82HE3%2F73/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to 1.5KE82HE3/73 in the same family?","answer":"A functionally similar TVS with the same 66.4 V standoff and 1500 W rating would require a new qualification — the AEC-Q101 pedigree is specific to this TransZorb series."},{"question":"What compliance documentation does Vishay provide for 1.5KE82HE3/73?","answer":"The part carries AEC-Q101 automotive qualification, which implies PPAP-level documentation and reliability test data per the standard.
