DMP21D0UT-7 from Diodes Incorporated, in a SOT-523. 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, ESD protected to 3kV by an internal gate protection diode; VGSS rating is ±8V and typical threshold VGS(th) is -0.7V. |
| 2 | S | passive | Source of the P-channel MOSFET, connected internally to the body diode and gate protection diode; drain-source voltage VDSS is -20V. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for continuous ID of -0.59A at TA = 25°C (Note 4) and VDSS of -20V. |
