This is a unidirectional suppressor — one channel, cathode-band oriented — so it protects a single DC rail or signal line against positive-going transients. ## DO-15 axial — board-mount and storage Housed in a DO-204AC (DO-15) axial-lead package, the P6KE400A-B is a through-hole part. The body is 0.034-inch diameter with 0.040-inch lead diameter — the leads are tin-plated copper, solderable into a 0.040-inch plated through-hole on a 0.100-inch grid. The junction operates from -55°C to 175°C, so it handles the thermal pulse of a 600W surge without derating at room ambient. Supplied in Bulk (tube or bag), not tape-and-reel — the leads are straight, not formed for surface mount. Store the reels dry: the DO-15 body is not moisture-sensitive, but the leads can oxidise in humid storage. No power line protection rating — this is a signal- or DC-rail suppressor, not an AC mains MOV replacement. ## Active production — sourcing posture No official second-source or pin-compatible cross-reference is listed, but the P6KE family (base number P6KE400) shares the same DO-15 footprint and 600W rating across multiple vendors.","metaTitle":"P6KE400A-B Diodes Inc TVS, 600W, 342V Standoff, DO-15","metaDescription":"P6KE400A-B Diodes Incorporated 600W Zener TVS diode, 342V reverse standoff, 548V clamping, DO-15 axial.
