# BF1107-VB

**VBsemi Elec** · MOSFETs · SOT-23(TO-236)

BF1107-VB from VBsemi Elec, in a SOT-23(TO-236). 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 | Gate | input | Gate terminal; gate-source voltage is rated ±20 V in the absolute maximum ratings. |
| 2 | Source | passive | Source terminal; drain-source breakdown voltage is 60 V minimum at VGS = 0 V and ID = 10 µA. |
| 3 | Drain | passive | Drain terminal; continuous drain current is 250 mA at TA = 25 °C and pulsed drain current is 800 mA. |

## CAD (KiCad official)

- Symbol: `BF1107-VB`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23(TO-236) (KiCad packages3D, STEP)
- 3D model files: `bf1107-vb-etched.step` / `bf1107-vb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bf1107-vb.step` / `bf1107-vb.glb` are the bare package body.
