# P6KE47A

**SUNMATE Elec** · TVS · DO-15

P6KE47A from SUNMATE Elec, 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 P6KE47A, marked by the color band; connect to the positive/protected line (standoff 40.2V, breakdown 44.7-49.4V at 1.0mA, clamp 64.8V at 9.3A). |
| 2 | A | passive | Anode end of the unidirectional P6KE47A (opposite the color band); connect to the return/ground side of the protected circuit. |
