DO3404BA from DOINGTER, in a SOT-23-3. 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; controls the channel, with VGS rated ±20 V maximum and threshold VGS(th) 1.2 V min to 2.3 V max at ID=250 µA. |
| 2 | D | passive | Drain; VDS rated 30 V maximum with continuous drain current of 5.8 A at TA=25℃ and pulsed drain current of 21 A. |
| 3 | S | passive | Source; connects to the body diode anode and the return path of the drain current (IS continuous 5.8 A). |
