DMN3051L-7

Diodes Incorporated · MOSFETs · SOT-23

DMN3051L-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 rated ±20 V maximum and a threshold of 1.3 V min to 2.2 V max at ID = 250 µA.
2 S passive Source; the body diode runs from source to drain, with maximum continuous body diode current IS of 2 A.
3 D passive Drain; VDSS is 30 V maximum, with continuous ID of 4.5 A steady state and 5.8 A for t<5s at TA = +25°C (VGS = 10 V).
