The DO-201AA / DO-27 axial through-hole package is a legacy footprint common in power distribution and battery-clamp circuits where the board sees mechanical strain — the lead bend absorbs vibration better than a surface-mount package in the same role.","metaTitle":"1.5KE12AHA0G TVS Diode, 1500W, 10.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE12AHA0G Zener TVS diode, 1500W peak pulse power, 10.2V reverse standoff, AEC-Q101 automotive qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5KE","Package":"Tape & Box (TB)","Applications":"Automotive","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE12","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"11.4V","Voltage - Clamping (Max) @ Ipp":"16.7V","Voltage - Reverse Standoff (Typ)":"10.2V","Current - Peak Pulse (10/1000µs)":"94A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4993","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5KE12AHA0G used for?","answer":"It is a 1500 W unidirectional Zener TVS diode used to clamp voltage transients on a 12 V nominal rail — typically in automotive ECUs, battery management, and industrial control boards where the 10.2 V standoff keeps the device out of conduction during normal operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE12AHA0G","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/1.5KE12AHA0G when reusing this data.
