FDN357N from onsemi, 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; logic-level control input, VGSS rated ±20 V continuous with RDS(ON) of 0.090 Ω at VGS = 4.5 V and 0.060 Ω at VGS = 10 V. |
| 2 | S | passive | Source terminal of the N-channel MOSFET, with a maximum continuous body-diode forward current of 0.42 A. |
| 3 | D | passive | Drain terminal, rated for VDSS of 30 V and 1.9 A continuous (10 A pulsed) drain current. |
