Comchip · TVS · DO-15
P6KE550A-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 | K | passive | Cathode end of the unidirectional TVS, marked by the colorband, which connects to the positive side of the protected line (VRWM 470.3 V, breakdown 522.50 to 577.50 V at 1 mA, maximum clamping 759.0 V). |
| 2 | A | passive | Anode end of the unidirectional TVS, which is the end without the colorband and connects to the return side of the protected line (600 W peak pulse power at 10/1000 µs, VF 5.0 V maximum at 50 A). |
