The device offers a minimum breakdown voltage of 209V and a maximum clamping voltage of 388V at the peak pulse current of 26A (8/20µs waveform), making it suitable for 188V nominal rail protection where the reverse standoff voltage is 188V. ## Package and mounting — through-hole axial DO-201 This part comes in a DO-201AA (also known as DO-27) axial-lead through-hole package. The body is cylindrical with leads on both ends, intended for hand insertion or wave soldering into plated through-holes on a PCB. The axial form factor is common in power-supply input stages and telecom line cards where the TVS is often mounted standing off the board or with formed leads. ## Lifecycle status — obsolete, sourced to order","metaTitle":"1.5KE220ARL TVS Diode, 1500W, 209V Breakdown, DO-201","metaDescription":"STMicroelectronics 1.5KE220ARL TRANSIL™ TVS, 1500W peak pulse, 209V min breakdown, 388V clamping, DO-201 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"1.5KE, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"1.5KE","Operating Temperature":"-","Power Line Protection":"No","Capacitance @ Frequency":"625pF @ 1MHz","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"209V","Voltage - Clamping (Max) @ Ipp":"388V","Voltage - Reverse Standoff (Typ)":"188V","Current - Peak Pulse (10/1000µs)":"26A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/089e26c8bbf5e28593f663899fc6cea1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE220ARL/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for 1.5KE220ARL?","answer":"There is no official manufacturer replacement listed for the 1.5KE220ARL. For a form-fit-function substitute, look for a 1500W unidirectional TVS in a DO-201 axial package with a 188V standoff voltage, 209V minimum breakdown, and 388V maximum clamping. Parts from the same 1.5KE series with different voltage ratings are not drop-in replacements.
