# P6KE33CA

**Suzhou Good-Ark Elec** · TVS · DO-204AC(DO-15)

P6KE33CA from Suzhou Good-Ark Elec, in a DO-204AC(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 | Axial solder-plated lead of the bidirectional (CA suffix) TVS; electrical characteristics apply in both directions, with no cathode band and 600W peak pulse power (10/1000us). |
| 2 | A2 | passive | Second axial solder-plated lead of the bidirectional (CA suffix) TVS; interchangeable with the other lead since characteristics apply in both directions. |
