# P6KE56A

**RUILON(Shenzhen Ruilongyuan Elec)** · TVS · DO-15

P6KE56A from RUILON(Shenzhen Ruilongyuan 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 (marked with cathode band on unidirectional P6KE56A); for the unidirectional part it is the positive side, with VRWM 47.80 V, VBR 53.20-58.80 V at 1 mA and VC 77.0 V max at 7.80 A (10/1000µs). |
| 2 | A | passive | Anode of the unidirectional P6KE56A TVS diode; forward voltage VF is 3.5/6.5 V at 25 A and peak forward surge current IFSM is 100 A (8.3 ms half sine). |
