DMN55D0UT-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 2kV with an internal gate protection diode; absolute maximum VGSS ±12V and threshold VGS(TH) 0.7V min to 1.0V max at ID = 250µA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET, with the body diode running to the drain (VSD 1.3V max at IS = 100mA). |
| 3 | D | passive | Drain terminal with VDSS of 50V and continuous drain current of 160mA. |
