UMW · MOSFETs · SOT-23
FDN361BN 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 terminal of the MOSFET; the datasheet gives a gate-source voltage rating of ±20 V (VGSS). |
| 2 | S | passive | SOURCE terminal of the MOSFET; the datasheet gives no source-specific limit beyond the device ratings. |
| 3 | D | passive | DRAIN terminal of the MOSFET; the datasheet gives a drain-source voltage rating of 30 V (VDSS) and continuous drain current of 1.4 A (Note 1a). |
