It handles 600 W peak pulse power (10/1000 µs waveform) and clamps at 27.2 V maximum, with a 12.8 V reverse standoff and a 14.3 V minimum breakdown. The DO-204AC (DO-15) axial-lead through-hole package suits board-level surge protection in industrial, telecom, and power-supply applications where a robust, leaded part is preferred over surface-mount. ## Voltage window and surge current The 12.8 V standoff means the line can run at 12 V nominal without leakage issues. Breakdown starts at 14.3 V, and clamping hits 27.2 V at the peak pulse current of 147 A (8/20 µs waveform). That 27.2 V ceiling protects downstream silicon rated for 30 V or higher — a common margin rule for 12 V rails. The 1900 pF capacitance at 1 MHz is typical for a 600 W TVS in this voltage class; it adds load on signal lines but is acceptable for power and low-speed I/O. STMicroelectronics lists the P6KE15ARL as obsolete. Buyers should qualify date code and lot traceability per their incoming inspection.","metaTitle":"STMicroelectronics P6KE15ARL Zener TVS, 600W, DO-15","metaDescription":"P6KE15ARL is a 600W Zener TVS diode from STMicroelectronics, 12.8V standoff, 27.2V clamp, DO-15 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"P6KE, TRANSIL™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-204AC, DO-15, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"P6KE","Operating Temperature":"-","Power Line Protection":"No","Capacitance @ Frequency":"1900pF @ 1MHz","Supplier Device Package":"DO-15 (DO-204AC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.3V","Voltage - Clamping (Max) @ Ipp":"27.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"147A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d21127580ed2e5c86eab4a11f0f1e77c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is P6KE15ARL a Zener diode?","answer":"Yes, the listed type is Zener, part of the P6KE / TRANSIL™ series for transient voltage suppression."},{"question":"What is the capacitance of P6KE15ARL?","answer":"Capacitance is 1900 pF measured at 1 MHz.
