It is designed for general-purpose transient overvoltage protection, with a reverse standoff voltage of 256V and a minimum breakdown voltage of 285V. The device clamps transients to a maximum of 529V at the peak pulse current of 7.6A (8/20 µs waveform), handling 600W of peak pulse power. This is a single-channel, unidirectional part — no bidirectional option in this package variant. The 529V clamping voltage is the peak the protected circuitry must survive without damage. With a 7.6A peak pulse current rating (8/20 µs), this part suits moderate-energy transients on 240V AC secondary-side rectified rails or 250V DC bus lines. The 290 pF capacitance at 1 MHz is typical for a TVS at this voltage — check it against signal integrity if used on a data line, though the primary application is power rail clamping. ## Lifecycle and procurement Cut Tape (CT) quantities are available alongside standard Tape & Reel (TR) packaging.","metaTitle":"STMicroelectronics P6KE300ARL TRANSIL TVS Diode","metaDescription":"STMicroelectronics P6KE300ARL is a 600W unidirectional TRANSIL Zener TVS diode in DO-15 axial package. 256V reverse standoff, 285V min breakdown, 529V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"P6KE, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-204AC, DO-15, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"P6KE300","Operating Temperature":"-","Power Line Protection":"No","Capacitance @ Frequency":"290pF @ 1MHz","Supplier Device Package":"DO-15 (DO-204AC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"285V","Voltage - Clamping (Max) @ Ipp":"529V","Voltage - Reverse Standoff (Typ)":"256V","Current - Peak Pulse (10/1000µs)":"7.6A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2455","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d21127580ed2e5c86eab4a11f0f1e77c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is P6KE300ARL a bidirectional TVS?","answer":"No. The P6KE300ARL is a unidirectional device with one channel.
