DO2300B 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 is limited to ±12 V absolute maximum, with threshold of 0.5 V min to 1 V max at ID=250μA. |
| 2 | D | passive | Drain; drain-source voltage is 20 V maximum with continuous drain current of 5.2 A and pulsed drain current of 20.8 A. |
| 3 | S | passive | Source; connected to the body diode anode with continuous diode current of 4 A maximum. |
