Slkor SLKORMICRO Elec · MOSFETs · SOT-23
SL3402 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 channel, with absolute maximum gate-source voltage of ±20 V and threshold VGS(TH) of 0.5 V min to 1.5 V max at ID=250μA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; body diode conducts source-to-drain up to 1.8 A continuous with VSD max 1.2 V. |
| 3 | D | passive | Drain terminal; drain-source breakdown voltage 30 V minimum, continuous drain current 4 A at TA=25°C. |
