The AEC-Q101 Grade 0 temperature range (-55 to 175 °C) suits under-hood or engine-bay environments where ambient heat cycles are severe. ## Through-hole axial package for board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE120AHE3/51 mounts through-hole — the leads are soldered into plated holes on the PCB. The axial body allows either vertical or horizontal placement, with the cathode band marking polarity. The 1.5KE package footprint is standard across the family, simplifying layout reuse. ## Sourcing an obsolete automotive TVS Vishay has marked the 1.5KE120AHE3/51 as obsolete. For BOM lines already qualified to this order code, supply is maintained through independent distribution — quantities and date codes are confirmed at the time of RFQ. The AEC-Q101 qualification and 1500 W rating remain the key fit criteria; if a board spin is feasible, a parametric cross-search on standoff voltage and package will identify active alternatives.","metaTitle":"Vishay 1.5KE120AHE3/51 TVS Diode, 1500W, 102V Standoff","metaDescription":"Obsolete Vishay 1.5KE120AHE3/51 automotive TVS diode, AEC-Q101, 1500W peak pulse, 102V standoff, 165V 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":"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":"1.5KE120","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"114V","Voltage - Clamping (Max) @ Ipp":"165V","Voltage - Reverse Standoff (Typ)":"102V","Current - Peak Pulse (10/1000µs)":"9.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the key clamping specifications for the 1.5KE120AHE3/51?","answer":"Peak pulse power is 1500 W."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE120AHE3-51","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/1.5KE120AHE3-51 when reusing this data.
