Slkor SLKORMICRO Elec · MOSFETs · SOT-23
SL3407 from Slkor SLKORMICRO Elec, 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 | G | input | Gate; controls the P-channel MOSFET, with a maximum gate-source voltage of ±20 V and threshold of -1 to -3 V. |
| 2 | S | passive | Source of the P-channel MOSFET; body diode forward voltage is at most -1.2 V at IS=-4.1 A. |
| 3 | D | passive | Drain; rated for VDS of -30 V and continuous drain current of -4.1 A (pulsed -20 A). |
