DO2021AA 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 of the P-channel MOSFET, with VGS limited to ±12 V and a threshold of -0.4 V to -1 V at 250 µA. |
| 2 | D | passive | Drain, rated for VDS of -20 V and continuous drain current of -7 A at TA=25℃. |
| 3 | S | passive | Source of the P-channel MOSFET, with body diode forward voltage of -1.2 V max at ISD=-7A. |
