DMN53D0LT-7

Diodes Incorporated · MOSFETs · SOT-523

DMN53D0LT-7 from Diodes Incorporated, in a SOT-523. 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; ESD protected to 2kV via an internal gate protection diode, with gate-source voltage limited to ±20V (VGSS) and threshold of 0.8V to 1.5V.
2 S passive Source terminal of the N-channel MOSFET, shown at the bottom right of the top view.
3 D passive Drain terminal of the N-channel MOSFET, rated for 50V VDSS and 350mA continuous drain current.

CAD (KiCad official)

  • Symbol: DMN53D0LT-7
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: dmn53d0lt-7-etched.step / dmn53d0lt-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dmn53d0lt-7.step / dmn53d0lt-7.glb are the bare package body.
