# BAR43FILM

**STMicroelectronics** · Schottky Barrier Diodes (SBD) · SOT-23-3L

BAR43FILM from STMicroelectronics, in a SOT-23-3L. 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 | A | passive | Anode of the single Schottky diode (BAR43FILM, marking D95), rated for 30 V VRRM and 0.1 A continuous forward current. |
| 2 | NC | unconnected | Not connected internally (labelled Nc on the BAR42FILM/BAR43FILM package drawing). |
| 3 | K | passive | Cathode of the single Schottky diode, with VF max 0.33 V at IF = 2 mA for the BAR43. |

## CAD (KiCad official)

- Symbol: `BAR43FILM`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `bar43film-etched.step` / `bar43film-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bar43film.step` / `bar43film.glb` are the bare package body.
