The 27A peak pulse current rating at 10/1000µs defines the surge it can absorb without failing short. ## Package, mounting, and board integration Supplied in DO-201AA / DO-27 axial leaded package, through-hole mount. The DO-201 supplier device package footprint is standard — the axial leads insert into plated through-holes and the body stands off the board. Tape & Reel packaging suits automated insertion for volume builds.","metaTitle":"1.5KE39CH TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE39CH bidirectional Zener TVS diode, 1500W peak pulse power, 31.6V standoff, AEC-Q101 automotive grade.","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":"General Purpose","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE39","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"35.1V","Voltage - Clamping (Max) @ Ipp":"56.4V","Voltage - Reverse Standoff (Typ)":"31.6V","Current - Peak Pulse (10/1000µs)":"27A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2712","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/032bc92052e6d2ce2c6b03bbf9447af3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What automotive qualification does 1.5KE39CH carry?","answer":"It is AEC-Q101 qualified, the automotive-grade stress and reliability standard for discrete semiconductors.
