The single bidirectional channel in a DO-201AA axial package handles both polarities in one device, saving board space over two unidirectional TVS diodes back-to-back. The -65°C to 150°C junction-temperature range covers military/aerospace thermal cycling without derating at the cold end. ## Lifecycle reality — obsolete, sourced through independent channels Microsemi has marked this part obsolete. No official successor order code is recorded, so the replacement path is either a pin-compatible TVS from another manufacturer with matching 324V standoff and 1500W rating, or a board-level change if the footprint differs.","metaTitle":"Microsemi 1.5KE400CAE3/TR13 TVS, 1500W, 324V, DO-201AA","metaDescription":"Obsolete Microsemi 1.5KE400CAE3/TR13 bidirectional Zener TVS. 1500W peak pulse, 324V standoff, 548V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microsemi Corporation","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","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":"1.5KE","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"CASE-1","Voltage - Breakdown (Min)":"380V","Voltage - Clamping (Max) @ Ipp":"548V","Voltage - Reverse Standoff (Typ)":"324V","Current - Peak Pulse (10/1000µs)":"4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE400CAE3%2FTR13/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to 1.5KE400CAE3/TR13?","answer":"A functional replacement would need to match 324V reverse standoff, 1500W peak pulse power, bidirectional polarity, and the DO-201AA axial footprint — confirm the pin-compatible candidate with the datasheet before specifying."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microsemi-corporation/1.5KE400CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microsemi-corporation/1.5KE400CAE3-TR13 when reusing this data.
