# P6KE180A

**SUNMATE Elec** · ESD And Surge Protection (TVS/ESD) · DO-15

P6KE180A 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, marked by the color band on the DO-15 axial package; for the unidirectional P6KE180A this is the end that is positive for normal reverse-biased (stand-off) operation, with stand-off voltage 154 V and breakdown 171-189 V at 1.0 mA. |
| 2 | A | passive | Anode, the axial lead opposite the color band on the DO-15 package; the unidirectional P6KE180A clamps at a maximum of 246 V at 2.4 A peak pulse current. |
