# SMF15A

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

SMF15A 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 | K | passive | Cathode of the unidirectional TVS, marked by the cathode band; for SMF15A the reverse standoff voltage is 15 V and breakdown is 16.7 V min to 18.5 V max at 1.0 mA. |
| 2 | A | passive | Anode of the unidirectional TVS; max clamping voltage is 24.4 V at 8.2 A peak pulse current and peak pulse power is 200 W (10x1000us). |

## CAD (KiCad official)

- Symbol: `SMF15A`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `smf15a-etched.step` / `smf15a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smf15a.step` / `smf15a.glb` are the bare package body.
