KY3407
KY · MOSFETs · SOT-23
KY3407 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 P-channel MOSFET; the gate-source voltage is rated VGSS = ±20 V. |
| 2 | SOURCE | passive | Source terminal of the MOSFET, the reference for VGS; the datasheet gives a body-diode forward current limit of IS = -4.1 A. |
| 3 | DRAIN | passive | Drain terminal of the MOSFET; drain-source voltage is rated VDSS = -30 V with continuous drain current ID = -4.1 A. |
