With a breakdown voltage range starting at 418V minimum, this part is sized for 360-400V nominal DC rails — think traction inverter DC links, industrial drive bus capacitors, or 277VAC rectified supplies where the peak is around 390V. ## DO-201 axial package and board integration Through-hole DO-201AA (DO-27) axial package — the leads are 0.96mm diameter tin-plated copper, spaced 8.9mm apart. The body is 5.3mm diameter, 7.5mm long. Mounting requires a 1.2mm hole per lead; keep the trace width to the anode and cathode at least 3mm to handle the 2.5A peak pulse current without trace lift.","metaTitle":"1.5KE440AH TVS Diode, 1500W, 376V Standoff, DO-201","metaDescription":"1.5KE440AH from Taiwan Semiconductor: 1500W peak pulse power, 376V reverse standoff, 602V clamping, 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","Series":"Automotive, AEC-Q101, 1.5KE","Package":"Tape & Reel (TR)","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":"1.5KE440","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"418V","Voltage - Clamping (Max) @ Ipp":"602V","Voltage - Reverse Standoff (Typ)":"376V","Current - Peak Pulse (10/1000µs)":"2.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5564","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/1.5KE440AH","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/1.5KE440AH when reusing this data.
