**DOINGTER** · MOSFETs · SOT-23

DO2305A-C from DOINGTER, 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 | G | input | Gate; P-channel gate-source voltage limited to ±12 V, threshold VGS(th) -0.4 V min to -1 V max at ID=250μA. |
| 2 | D | passive | Drain; drain-source voltage rated -15 V, continuous drain current -5.5 A at TA=25℃ and pulsed -16 A. |
| 3 | S | passive | Source; connects to the drain through the body diode, with continuous diode current IS of -4.1 A max. |

## CAD (KiCad official)

- Symbol: `DO2305A-C`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `do2305a-c-etched.step` / `do2305a-c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `do2305a-c.step` / `do2305a-c.glb` are the bare package body.
