It clamps surges at 64.3 V maximum while standing off 30.8 V DC continuously, making it a fit for protecting 28 V to 36 V power buses, telecom line cards, and industrial control inputs against lightning and inductive load transients. Rated for 1500 W peak pulse power at 10/1000 µs, the device handles 156 A peak pulse current under the 8/20 µs waveform. The DO-201AA axial lead package suits through-hole board mounting with a robust solder joint for high-surge applications. ## Clamping voltages and surge rating Breakdown starts at 34.2 V minimum, and clamping to 64.3 V at full rated current limits the voltage spike seen by the protected circuitry. The 1500 W peak pulse power rating applies to the standard 10/1000 µs waveform; the 156 A figure is for the 8/20 µs waveform, a common lightning-surge test condition. No power line protection rating — the part is intended for signal and low-power DC rail clamping, not AC mains input. Capacitance of 2500 pF at 1 MHz is typical for a 1.5 kW Zener TVS and should be considered for high-speed data lines where signal integrity matters.","metaTitle":"1.5KE36ARL STMicroelectronics Zener TVS Diode, 1500W, DO-201","metaDescription":"1.5KE36ARL STMicroelectronics Zener TVS diode, 1500W peak pulse power, 30.8V standoff, 64.3V 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)","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":"2500pF @ 1MHz","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"34.2V","Voltage - Clamping (Max) @ Ipp":"64.3V","Voltage - Reverse Standoff (Typ)":"30.8V","Current - Peak Pulse (10/1000µs)":"156A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/089e26c8bbf5e28593f663899fc6cea1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE36ARL/alternatives.json"},"ai":{"faq":[{"question":"What is a suitable replacement for 1.5KE36ARL?","answer":"No official replacement is listed by STMicroelectronics. A functionally equivalent unidirectional TVS diode with a 30.8 V standoff and 1500 W rating in a DO-201 package, such as the 1.5KE36A (without the RL suffix), may be a pin-compatible alternative — verify breakdown and clamp voltages against the design requirements before substitution."},{"question":"Is 1.5KE36ARL RoHS compliant?","answer":"The evidence does not specify RoHS compliance for this order code.
