KY · MOSFETs · SOT-23
KY2301H 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 MOSFET; the datasheet rates the gate-source voltage VGSS at ±12 V for this device. |
| 2 | SOURCE | passive | Source terminal of the MOSFET; the datasheet rates this -20 V P-channel device with a drain-source voltage VDSS of -20 V and a continuous drain current ID of -3 A. |
| 3 | DRAIN | passive | Drain terminal of the MOSFET; the datasheet gives a pulsed drain current IDM of -12 A for this device. |
