2SK1658 from Changjing, in a SOT-323. 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 terminal of the N-channel MOSFET, limited to a gate-source voltage VGS of ±7 V. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, the reference for the 30 V drain-source and ±7 V gate-source ratings. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for 30 V drain-source voltage and 0.1 A continuous drain current. |
