5KP7.5A from Littelfuse, 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 | Axial lead at the cathode end, marked by the color band on unidirectional parts; for 5KP7.5A the reverse stand-off voltage VR is 7.5 V and breakdown voltage VBR is 8.33 V min to 9.21 V max at 5 mA. |
| 2 | Anode | passive | Axial lead at the end opposite the cathode band; for 5KP7.5A the maximum clamping voltage is 12.9 V at 395.3 A peak pulse current (10/1000μs). |
