P4SOD5.0AX from WeEn Semiconductors, in a SOD-123. 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 of the uni-directional TVS, marked by the cathode band; connect to the protected line (positive side), where the part clamps at VC 9.2 V max at 43.5 A Ipp, VR 5 V. |
| 2 | A | passive | Anode of the uni-directional TVS; connect to ground or the return side of the protected line, with 400 W peak pulse power at 10/1000 µs. |
