# SMF14CA

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

SMF14CA from AnBon, 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 (SMF14CA, no polarity band); the datasheet gives no pin names or limits for the bi-directional part, and the pin 1 side is the cathode only on uni-directional parts. |
| 2 | 2 | passive | Bi-directional TVS terminal (SMF14CA, no polarity band); the datasheet gives no pin names or limits for the bi-directional part, and the pin 2 side is the anode only on uni-directional parts. |

## CAD (KiCad official)

- Symbol: `SMF14CA`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `smf14ca-etched.step` / `smf14ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smf14ca.step` / `smf14ca.glb` are the bare package body.
