# P6KE350A

**DOWO** · TVS · DO-15

P6KE350A from DOWO, in a 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 | K | passive | Cathode end of the unidirectional TVS, marked by the color band; connect to the positive side of the protected line (P6KE350A: VRWM 299.3 V, VBR 332.5-367.5 V at 1 mA, VC 482 V at IPP 1.24 A). |
| 2 | A | passive | Anode end of the unidirectional TVS (no band); connect to the return or ground side, with 600 W peak pulse power on a 10/1000 µs waveform. |
