P6KE520CA-HF from Comchip, in a DO-15. 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 terminal 1 of the P6KE520CA-HF (VBR 494 to 546 V at 1 mA, VRWM 444.6 V, VC 717.6 V max at IPP 0.84 A); the datasheet states the color band denotes the cathode end except bipolar, so this terminal has no polarity. |
| 2 | A2 | passive | Bidirectional terminal 2 of the P6KE520CA-HF (VBR 494 to 546 V at 1 mA, VRWM 444.6 V, VC 717.6 V max at IPP 0.84 A); interchangeable with terminal 1 since bipolar devices carry no cathode band. |
