# DO2310A

**DOINGTER** · MOSFETs · SOT-23

DO2310A 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; gate-source voltage limited to ±20 V with threshold VGS(th) of 1 V min to 2.5 V max at ID=250μA. |
| 2 | D | passive | Drain; drain-source voltage up to 60 V, continuous drain current 3.5 A and pulsed drain current 14 A. |
| 3 | S | passive | Source; connects to the return of the N-channel MOSFET, with continuous body-diode current of 3.5 A max. |

## CAD (KiCad official)

- Symbol: `DO2310A`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `do2310a-etched.step` / `do2310a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `do2310a.step` / `do2310a.glb` are the bare package body.
