The 64.8V clamp at 23.2A keeps the downstream DC-DC input within its abs-max rating for a typical 75V bus converter. ## Package and deployment in harsh environments Housed in a DO-201AA / DO-27 axial-lead package (CASE-1), the 1.5KE47AE3/TR13 is a through-hole device — it solders into a board with a single drilled hole per lead and handles the thermal cycling of outdoor or industrial enclosures without solder-joint fatigue. The Tape & Reel packaging indicates this variant ships on a reel for automated insertion, though the through-hole format still requires a wave-solder or selective-solder step rather than reflow. ## Obsolete — sourcing through independent channels Microsemi has marked the 1.5KE47AE3/TR13 as Obsolete. For a BOM that requires this exact clamping voltage and package, the procurement path is a spot-market search against the 1.5KE47AE3/TR13 order code. A board-spin replacement would need a functionally equivalent 1500W unidirectional TVS with a 40V standoff and 64.8V clamp in an axial-lead DO-201 package — several manufacturers offer parametric matches, but pinout and footprint are identical across the DO-201 standard.","metaTitle":"1.5KE47AE3/TR13 Microsemi Zener TVS, 1500W, 64.8V Clamp","metaDescription":"Obsolete Microsemi 1.5KE47AE3/TR13 Zener TVS diode, 1500W peak pulse, 64.8V clamping, DO-201AA axial.","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","Capacitance @ Frequency":"-","Supplier Device Package":"CASE-1","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"44.7V","Voltage - Clamping (Max) @ Ipp":"64.8V","Voltage - Reverse Standoff (Typ)":"40.2V","Current - Peak Pulse (10/1000µs)":"23.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5KE47AE3/TR13?","answer":"The 1.5KE47AE3/TR13 is obsolete per Microsemi."},{"question":"What package does the 1.5KE47AE3/TR13 use?","answer":"It uses a DO-201AA / DO-27 axial-lead through-hole package (CASE-1)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microsemi-corporation/1.5KE47AE3-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/1.5KE47AE3-TR13 when reusing this data.
