# KY2310L

**KY** · MOSFETs · SOT-23

KY2310L from KY, 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 terminal of the 60 V N-channel MOSFET, with gate-source voltage rated at ±20 V (VGSS). |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; the datasheet gives no pin-specific limit, with the device rated for 60 V drain-source (VDSS) and 3 A continuous drain current. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for 60 V drain-source voltage (VDSS) and 3 A continuous drain current (ID). |
