P4KE6.8CA from DOWO, 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 | Bidirectional (CA suffix) terminal with no polarity and no color band; clamps transients of either polarity, with VBR 6.46 to 7.14 V at 10 mA and VC 10.5 V max at IPP 38.10 A. |
| 2 | A2 | passive | Second bidirectional terminal, interchangeable with the other lead; the part is rated for 400 W peak pulse power (10/1000 µs) and VRWM 5.8 V. |
