SL4409N

Slkor SLKORMICRO Elec · MOSFETs · SOT-323

SL4409N from Slkor SLKORMICRO Elec, in a SOT-323. 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 N-channel MOSFET; the datasheet rates gate-source voltage VGS at ±10 V.
2 SOURCE passive Source terminal of the N-channel MOSFET; the datasheet rates continuous source-drain (diode conduction) current IS at 0.6 A.
3 DRAIN passive Drain terminal of the N-channel MOSFET; the datasheet rates drain-source voltage VDS at 20 V and continuous drain current ID at 2.3 A.
