15KPA70A-B 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 | Cathode axial lead of the unidirectional 15KPA70A TVS diode, marked by the color band on the P600 body; stand-off voltage VR is 70 V and breakdown VBR is 78.2 to 85.6 V at 5 mA. |
| 2 | Anode | passive | Anode axial lead of the unidirectional 15KPA70A TVS diode at the end opposite the cathode band, with maximum clamping voltage of 113.6 V at 132.9 A peak pulse current. |
