This is a unidirectional Zener TVS, so it clamps positive transients only; a bidirectional device would be needed for AC lines or reverse-polarity protection. ## DO-201 axial — field-serviceable through-hole package The DO-201AA (DO-27) axial-lead package is through-hole mount — no hot-air station needed, just a soldering iron and a steady hand. The body is large enough to read the marking without a loupe, and the polarity band is clear.","metaTitle":"1.5KE56A-T Diodes Inc Zener TVS, 1500W, DO-201, Obsolete","metaDescription":"Diodes Inc 1.5KE56A-T Zener TVS diode, 1500W peak pulse power, 47.8V standoff, 77V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","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":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE56","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"53.2V","Voltage - Clamping (Max) @ Ipp":"77V","Voltage - Reverse Standoff (Typ)":"47.8V","Current - Peak Pulse (10/1000µs)":"19.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6b9d4121cb66208511919f4a66769e1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the 1.5KE56A-T?","answer":"A functional replacement would need to match the 1500 W peak pulse rating, 47.8 V standoff, and DO-201 axial package — but a board spin or BOM update may be required since no drop-in is documented."},{"question":"What compliance documentation does Diodes Incorporated provide for the 1.5KE56A-T?","answer":"Standard Diodes Incorporated TVS diodes typically carry RoHS and REACH compliance, but the exact documentation set should be confirmed at RFQ against the specific date code and lot."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/1.5KE56A-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/1.5KE56A-T when reusing this data.
