The part delivers 1500W peak pulse power per the 10/1000 µs waveform, with a breakdown voltage of 58.9V and a clamping voltage of 111V at the rated peak pulse current of 90A (8/20 µs waveform). It comes in a through-hole DO-201AA / DO-27 axial package, suitable for board-level protection where a soldered leaded device is preferred over surface-mount. The 1500W rating (10/1000 µs) tells you the device can absorb a single high-energy transient without failing. For a 53V standoff voltage, that translates to a substantial surge-handling margin on a 48V nominal bus or a 48V telecom line. The 1700pF capacitance at 1 MHz is non-trivial; on high-speed data lines it will load the signal, so this part is better suited to power-supply or low-frequency protection than gigabit Ethernet or USB 3.0. STMicroelectronics lists the 1.5KE62ARL as obsolete.","metaTitle":"1.5KE62ARL TRANSIL™ Zener TVS, 1500W, DO-201, Obsolete","metaDescription":"1.5KE62ARL is a 1500W unidirectional Zener TVS diode from STMicroelectronics. 58.9V breakdown, 53V standoff, 111V clamp.","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":"1700pF @ 1MHz","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"58.9V","Voltage - Clamping (Max) @ Ipp":"111V","Voltage - Reverse Standoff (Typ)":"53V","Current - Peak Pulse (10/1000µs)":"90A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/089e26c8bbf5e28593f663899fc6cea1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE62ARL/alternatives.json"},"ai":{"faq":[{"question":"Is 1.5KE62ARL equivalent to 1.5KE62A?","answer":"Yes, the 1.5KE62A is functionally equivalent. The RL suffix on the 1.5KE62ARL indicates Tape & Reel packaging; the 1.5KE62A is the same Zener TVS die in the same DO-201 axial package, just without that packaging suffix. Both share the same 58.9V breakdown, 53V standoff, and 1500W rating."},{"question":"What is a direct replacement for 1.5KE62ARL?","answer":"The closest direct replacement is the 1.5KE62A (same ST part, without the RL packaging suffix). For a different manufacturer alternative, look for a 1500W, 53V standoff, unidirectional TVS in a DO-201 package from Littelfuse or Vishay — for example, the 1.5KE62A from those brands is pin-compatible and electrically equivalent."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/1.5KE62ARL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/1.5KE62ARL when reusing this data.
