# SMFJ10CA

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

SMFJ10CA 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 with no polarity (SMFJ10CA: VRWM 10 V, VBR 11.1-12.3 V at 1.0 mA, VC 17.0 V at IPP 11.8 A); the datasheet shows the Pin 1 cathode assignment only for uni-directional parts. |
| 2 | 2 | passive | Bi-directional TVS terminal with no polarity (SMFJ10CA: VRWM 10 V, VBR 11.1-12.3 V at 1.0 mA, VC 17.0 V at IPP 11.8 A); the datasheet shows the Pin 2 anode assignment only for uni-directional parts. |

## CAD (KiCad official)

- Symbol: `SMFJ10CA`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `smfj10ca-etched.step` / `smfj10ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smfj10ca.step` / `smfj10ca.glb` are the bare package body.
