The reverse standoff voltage of 185V means the diode draws negligible leakage below that level; the breakdown voltage range (209V min) is where it starts conducting. ## Obsolete — sourcing reality for the 1.5KE220A-T Diodes Incorporated lists the 1.5KE220A-T as obsolete. For a BOM that already uses this TVS, the through-hole DO-201AA/DO-27 axial package (also called DO-201) is a standard footprint. If a board spin is acceptable, a functional replacement from the same 1.5KE family with a different standoff voltage may be considered, but the 1.5KE220A-T itself is the exact order code for the 185V standoff / 328V clamp specification. ## Temperature range and package fit The through-hole axial package (DO-201) is hand-solderable and fits standard 0.100-inch pitch prototyping boards, but for production runs the Tape & Reel packaging supports automated insertion. Power line protection is marked 'No' — this TVS is intended for DC rail protection, not AC mains. The unidirectional channel (one) means it clamps only one polarity; for AC or bidirectional protection, a pair would be needed back-to-back.","metaTitle":"1.5KE220A-T Diodes Inc Zener TVS, 1500W, 328V Clamp","metaDescription":"1.5KE220A-T from Diodes Incorporated is an obsolete Zener TVS diode, 1500W peak pulse, 328V clamping, DO-201 package.","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":"1.5KE220","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"209V","Voltage - Clamping (Max) @ Ipp":"328V","Voltage - Reverse Standoff (Typ)":"185V","Current - Peak Pulse (10/1000µs)":"4.6A"}},"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 1.5KE220A-T?","answer":"The 1.5KE family includes other standoff voltages (e.g., 1.5KE200A, 1.5KE250A) in the same DO-201 package, but the 1.5KE220A-T is the exact code for 185V standoff / 328V clamp.
