**Brightking** · ESD And Surge Protection (TVS/ESD) · DO-204AC(DO-15)

P6KE300A from Brightking, in a DO-204AC(DO-15). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | passive | Cathode end of the unidirectional P6KE300A, identified by the color band on the body; it clamps at a maximum 414 V at 1.5 A peak pulse current with a reverse stand-off voltage of 256 V and 600 W peak pulse power rating (10/1000 µs waveform). |
| 2 | A | passive | Anode end of the unidirectional P6KE300A, opposite the cathode band, where the reverse breakdown range is 285 V to 315 V at a 1 mA test current. |
