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

SMF120CA 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 | Bidirectional TVS terminal with no polarity (the C suffix denotes bi-directional); for SMF120CA the reverse standoff voltage is 120 V and the breakdown voltage is 133 V min to 147 V max at 1.0 mA. |
| 2 | 2 | passive | Bidirectional TVS terminal with no polarity and no cathode band; for SMF120CA the max clamping voltage is 193 V at 1.1 A peak pulse current and max leakage is 5.0 uA at VRWM. |

## CAD (KiCad official)

- Symbol: `SMF120CA`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `smf120ca-etched.step` / `smf120ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smf120ca.step` / `smf120ca.glb` are the bare package body.
