# BAR46AFILM

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

BAR46AFILM from STMicroelectronics, in a SOT-23. 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 | K1 | passive | Cathode of diode 1 of the BAR46A dual Schottky pair, rated for 100 V repetitive peak reverse voltage and 150 mA continuous forward current. |
| 2 | K2 | passive | Cathode of diode 2 of the BAR46A dual Schottky pair, rated for 100 V repetitive peak reverse voltage and 150 mA continuous forward current. |
| 3 | A | passive | Common anode of both Schottky diodes, where total power dissipation of both diodes is limited to 230 mW at Tamb = 25°C. |

## CAD (KiCad official)

- Symbol: `BAR46AFILM`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bar46afilm-etched.step` / `bar46afilm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bar46afilm.step` / `bar46afilm.glb` are the bare package body.
