When a surge hits, breakdown starts at 209V minimum and the diode hard-clamps at 328V maximum while shunting 4.6A of peak pulse current in the standard 10/1000µs waveform. That 328V ceiling is the voltage the downstream MOSFET, capacitor, or IC must survive; if your load's abs-max rating is below that, this diode alone won't protect it. With a single bidirectional channel, this one device handles both positive and negative transients on the same line — no need for two unidirectional diodes in anti-series, which saves board area and cuts the parts count on a 185V bus. ## Obsolete — sourcing reality for this TVS Diodes Incorporated lists the 1.5KE220CA-T as obsolete. No factory orders, no last-time-buy window remains open. Supply is limited to surplus and broker inventory held by independent distributors — the date-code mix and lot traceability vary by lot, so each RFQ is confirmed against what is physically available. No official successor order code is published by Diodes; a functional replacement from the same 1.5KE family would require verifying the standoff voltage, clamping, and package match against the BOM's protection requirement. ## Package and deployment context Through-hole DO-201AA / DO-27 axial package — a standard footprint that has been in production for decades. No board-spin risk for a replacement with the same body; the lead spacing and hole diameter are industry-common for this power class.","metaTitle":"1.5KE220CA-T Diodes Inc 1500W Bidirectional TVS","metaDescription":"1.5KE220CA-T from Diodes Incorporated — 1500W bidirectional TVS diode, 185V standoff, 328V clamp, 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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","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 are the key clamping specs for the 1.5KE220CA-T?","answer":"185V reverse standoff, 209V minimum breakdown, 328V maximum clamping at 4.6A peak pulse current in the 10/1000µs waveform.
