Leiditech · MOSFETs · SOT-323-3

DMN601WKQ from Leiditech, in a SOT-323-3. 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, limited to ±20 Vdc continuous and ±40 Vdc non-repetitive (tp≤50µs), with a gate threshold voltage of 1.0 to 2.5 Vdc at ID = 250 µAdc.
2 Source passive Source terminal of the MOSFET, which carries up to 115 mAdc continuous source (body diode) current and 800 mAdc pulsed.
3 Drain passive Drain terminal of the MOSFET, rated for 60 Vdc drain-source voltage and ±115 mAdc continuous drain current at TC = 25°C (±800 mAdc pulsed).
