# P6KE43CA

**DOWO** · TVS · DO-15

P6KE43CA from DOWO, 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 TVS terminal 1 (axial lead); P6KE43CA has VBR 40.85 to 45.15 V at 1 mA, VRWM 36.8 V, VC 59.3 V at IPP 10.12 A, and no polarity because the device is bidirectional. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (axial lead); interchangeable with terminal 1, with 600 W peak pulse power (10/1000 µs) and a -55 to +150 °C operating range. |
