# SJD12C06L01

**FUXINSEMI** · ESD And Surge Protection (TVS/ESD) · SOD-123

SJD12C06L01 from FUXINSEMI, in a SOD-123. 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 | 1 | passive | Bi-directional TVS terminal (SJD12C06L01, VRWM 6.0V, VBR 6.67-7.37V at 10mA, VC 10.3V at IPP 19.4A); the datasheet draws no polarity band or pin labels for the bi-directional device, so this terminal is interchangeable with the other. |
| 2 | 2 | passive | Bi-directional TVS terminal (SJD12C06L01, 200W peak pulse power at 10x1000us); the datasheet draws no polarity band or pin labels for the bi-directional device, so this terminal is interchangeable with the other. |
