# BAR18FILM

**STMicroelectronics** · Schottky Diodes · SOT-23-3

BAR18FILM from STMicroelectronics, in a SOT-23-3. 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 (VRRM 70 V, continuous forward current IF 70 mA). |
| 2 | N.C. | unconnected | No internal connection. |
| 3 | K | passive | Cathode of the single Schottky diode (VRRM 70 V, continuous forward current IF 70 mA). |

## CAD (KiCad official)

- Symbol: `BAR18FILM`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3 (KiCad packages3D, STEP)
- 3D model files: `bar18film-etched.step` / `bar18film-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bar18film.step` / `bar18film.glb` are the bare package body.
