KY · MOSFETs · SOT-23
KY3415B 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, rated for a gate-source voltage VGSS of ±10 V with a gate threshold of -0.4 V to -1.0 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the datasheet gives no separate pin-specific limit for this pin. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET, rated for a drain-source voltage VDSS of -20 V and continuous drain current of -4 A at TC = 25℃. |
