DMN3300UQ-7

Diodes Incorporated · MOSFETs · SOT-23-3

DMN3300UQ-7 from Diodes Incorporated, in a SOT-23-3. 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 G input Gate terminal of the N-channel MOSFET; gate-source voltage is rated ±12V with a threshold of 0.5V to 1V at 250µA.
2 S passive Source terminal of the N-channel MOSFET; body diode continuous current is rated 1.6A.
3 D passive Drain terminal of the N-channel MOSFET; drain-source voltage is rated 30V and continuous drain current is 2.0A at TA=+25°C.

CAD (KiCad official)

  • Symbol: DMN3300UQ-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.975 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: dmn3300uq-7-etched.step / dmn3300uq-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dmn3300uq-7.step / dmn3300uq-7.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (6 pp, sha256 d8aa000ddab26c55, retrieved 2026-11-12, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
