5KP22A
WPMtek(Wei Pan Microelectronics) · ESD And Surge Protection (TVS/ESD) · P600
5KP22A from WPMtek(Wei Pan Microelectronics), in a P600. 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 | Cathode | passive | Cathode terminal of the uni-directional TVS, marked by the color band (VR 22.0V, VBR 24.00-26.90V at 5mA, VCL 35.5V at IPP 143.7A); for bi-directional models the polarity band is absent and the two terminals are interchangeable. |
| 2 | A | passive | Anode terminal of the axial-lead TVS at the end opposite the color band (5000W peak pulse power at 10/1000μs, IR max 2μA at VR 22.0V). |
