The reverse standoff voltage is 7.78 V typical, meaning the diode draws negligible leakage below that level and only conducts when the line exceeds the 8.65 V minimum breakdown threshold. This part carries AEC-Q101 qualification, the automotive-grade stress test for discrete semiconductors. The DO-201AA axial package (also known as DO-27) is a through-hole body with a 0.052-inch diameter lead. ## Active production and sourcing posture The base product number 1.5KE9.1 identifies the 9.1 V breakdown family; the AHR0G suffix denotes the automotive grade, AEC-Q101 qualification, and tape-and-reel packaging.","metaTitle":"1.5KE9.1AHR0G TVS Diode, 1500W, 7.78V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE9.1AHR0G automotive TVS diode. 1500W peak pulse power, 7.78V reverse standoff, DO-201 axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE9.1","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"8.65V","Voltage - Clamping (Max) @ Ipp":"13.4V","Voltage - Reverse Standoff (Typ)":"7.78V","Current - Peak Pulse (10/1000µs)":"117A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE9.1AHR0G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5KE9.1AHR0G when reusing this data.
