FDN359AN from UMW, 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 of the N-channel MOSFET; the datasheet gives VGSS = ±20 V as the maximum gate-source voltage. |
| 2 | S | passive | SOURCE of the N-channel MOSFET; the datasheet gives no pin-specific limit, and the device is rated VDSS = 30 V with continuous ID = 2.7 A. |
| 3 | D | passive | DRAIN of the N-channel MOSFET; the datasheet gives VDSS = 30 V and continuous ID = 2.7 A (Note 1a), and states that the thermal reference is the solder mounting surface of the drain pins. |
