# SMF11CA

**JSMSEMI** · TVS · SOD-123FL

SMF11CA from JSMSEMI, in a SOD-123FL. 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 | Cathode | passive | PINNING table lists pin 1 as Cathode for the unipolar parts; the SMF11CA is the bidirectional (CA) variant, whose symbol shows no polarity, so pin 1 is interchangeable with pin 2 in the bipolar configuration. |
| 2 | Anode | passive | PINNING table lists pin 2 as Anode for the unipolar parts; for the bidirectional SMF11CA the symbol shows no polarity, so pin 2 is interchangeable with pin 1. |

## CAD (KiCad official)

- Symbol: `SMF11CA`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `smf11ca-etched.step` / `smf11ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smf11ca.step` / `smf11ca.glb` are the bare package body.
