For a 12 V automotive bus, this part triggers well below the nominal rail — it is sized for low-voltage supply protection, not the main 12 V line. ## AEC-Q101 and the automotive deployment envelope The operating junction temperature range is -55°C to 175°C, which covers under-hood and engine-bay environments where ambient temperatures can exceed 125°C. The DO-201AA axial-lead package is a through-hole form factor — it suits point-to-point wiring on terminal strips or PCB mounting where the lead bend radius is controlled to avoid cracking the glass passivation.","metaTitle":"1.5KE8.2AHE3/51 Vishay TVS, 1500W, 12.1V Clamp, Obsolete","metaDescription":"Vishay 1.5KE8.2AHE3/51 unidirectional TVS diode, 1500W peak pulse, 12.1V clamp, AEC-Q101.","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":"Bulk","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":"1.5KE8.2","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","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":"$0.5346","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE8.2AHE3-51","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE8.2AHE3-51 when reusing this data.
