Its 285 V minimum breakdown voltage means the device starts conducting when the line exceeds that threshold, and the 414 V maximum clamping voltage at the 1.45 A peak pulse current (10/1000 µs waveform) defines the highest voltage the protected load sees during a surge event. ## Lifecycle and procurement reality This part is marked Obsolete by the manufacturer. For a BOM manager evaluating a repair or legacy-production run, the 600 W rating and the DO-15 axial footprint are the two parameters to match when selecting a functional replacement; a board spin may be required if a pin-compatible drop-in is not available. ## Package and integration note The through-hole mount is straightforward for hand-assembly or wave-solder lines — the axial leads insert into plated through-holes and the body sits above the board, allowing natural convection cooling during pulse events. The DO-15 footprint is a common form factor across TVS families, so PCB layout for this part is standard and easily adapted to alternate suppliers if needed.","metaTitle":"P6KE300A-T Diodes Inc TVS, 600W, 414V Clamp, DO-15, Obsolete","metaDescription":"P6KE300A-T from Diodes Inc: 600W peak pulse power, 414V clamping at 1.45A, DO-15 axial.
