**AnBon** · MOSFETs · SOT-23

AS3423 from AnBon, 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 | GATE | input | Gate terminal of the P-channel MOSFET, with gate threshold VGS(th) of -0.65 V to -1.4 V and gate-source voltage rated +10 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the datasheet gives no pin-specific limit beyond the device drain-source voltage rating of -20 V. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET, rated for -20 V drain-source voltage and -2 A continuous drain current at Ta=25℃. |

## CAD (KiCad official)

- Symbol: `AS3423`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `as3423-etched.step` / `as3423-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `as3423.step` / `as3423.glb` are the bare package body.
