# P4KE8.2CA

**Brightking** · ESD And Surge Protection (TVS/ESD) · DO-41

P4KE8.2CA from Brightking, in a DO-41. 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 | A1 | passive | First axial lead of the bi-directional TVS; the datasheet gives no cathode band on bi-directional models, so the leads are interchangeable (VRWM 7.02V, VBR 7.79~8.61V at 10mA, VC 12.1V at 33.9A). |
| 2 | A2 | passive | Second axial lead of the bi-directional TVS; the datasheet gives no cathode band on bi-directional models, so the leads are interchangeable (400W peak pulse power at 10/1000μs). |
