It clamps at 706 V maximum under the 8/20 µs pulse shape, with a peak pulse power rating of 600 W. The 342 V reverse standoff voltage means it stays transparent on a nominal 300–340 V bus, only conducting once the transient exceeds the 380 V minimum breakdown threshold. Packaged in a DO-15 (DO-204AC) axial through-hole body, it suits telecom, industrial, and power-supply secondary-side protection where a bidirectional clamp simplifies layout. ## Obsolete — last-time-buy already closed The P6KE400CARL is marked Obsolete by STMicroelectronics. No last-time-buy window remains open through the factory channel. Sourcing now runs through independent distribution, where date-code provenance and stock authenticity are the buyer's main risk. ## DO-15 axial package — mounting and thermal notes Through-hole DO-15 (DO-204AC) axial body. Lead spacing and hole diameter follow the standard DO-15 footprint. The 600 W peak pulse rating assumes a 25 °C ambient with the leads soldered into a PCB with adequate copper pad area for heat sinking. Derate linearly above 25 °C per the TRANSIL series curve. No power line protection feature — this is a straight transient clamp, not a filtered or coordinated protector. ## Bidirectional — one device for bipolar transients A single bidirectional channel handles both positive and negative overvoltage events, which saves a diode and board area compared to back-to-back unidirectional Zeners. The 180 pF typical capacitance at 1 MHz is high enough to load a high-speed data line, but acceptable for power rails, relay coils, or low-frequency signal lines where the 342 V standoff is needed.","metaTitle":"STMicroelectronics P6KE400CARL TRANSIL TVS","metaDescription":"STMicroelectronics P6KE400CARL bidirectional Zener TVS diode, 600W peak pulse power, 342V standoff, 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); Cut Tape (CT)","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","Bidirectional Channels":"1","Capacitance @ Frequency":"180pF @ 1MHz","Supplier Device Package":"DO-15 (DO-204AC)","Voltage - Breakdown (Min)":"380V","Voltage - Clamping (Max) @ Ipp":"706V","Voltage - Reverse Standoff (Typ)":"342V","Current - Peak Pulse (10/1000µs)":"5.7A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d21127580ed2e5c86eab4a11f0f1e77c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is P6KE400CARL obsolete?","answer":"Yes, STMicroelectronics lists the P6KE400CARL as Obsolete.
