MDD2305 from MDD Microdiode Semiconductor, 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 terminal of the P-channel MOSFET, with gate-source voltage rated at VGS ±10 V. |
| 2 | S | passive | Source terminal of the MOSFET, serving as the reference for VGS and the source of the body diode, which is rated at ISD -2 A. |
| 3 | D | passive | Drain terminal of the MOSFET, rated for drain-source voltage VDS -20 V and continuous drain current ID -4.2 A. |
