MDD3415 from MDD（Microdiode Electronics）, 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 | Gate | input | Gate of the -20V P-channel enhancement MOSFET, with gate-source voltage limited to ±8 V and threshold VGS(th) of -0.4 V to -1.2 V at VDS = VGS, ID = -250 µA. |
| 2 | Source | passive | Source of the MOSFET; the body diode continuous source-drain current IS is rated -2.0 A at TC = 25 °C. |
| 3 | Drain | passive | Drain of the MOSFET, rated V(BR)DSS -20 V with continuous drain current ID of -4.8 A at TA = 25 °C (pulsed -30 A). |
