DMN3110S-7

Diodes Incorporated · MOSFETs · SOT-23

DMN3110S-7 from Diodes Incorporated, 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; drives the N-channel MOSFET, with VGS(th) 1.0 to 3.0 V and an absolute maximum VGSS of ±20 V.
2 S passive Source; connects to the source terminal of the N-channel MOSFET, with a body-diode forward voltage VSD of 1.0 V max at IS = 1 A.
3 D passive Drain; connects to the drain terminal of the N-channel MOSFET, rated for VDSS 30 V and continuous drain current up to 3.3 A (Note 6, TA = +25°C, VGS = 10 V).
