HYG030N03LQ1B

HUAYI · MOSFETs · TO-263-2L

HYG030N03LQ1B from HUAYI, in a TO-263-2L. 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 with a maximum gate-source voltage of ±20 V and a typical gate threshold of 1.3 V (1.0 to 3.0 V).
2 D passive Drain terminal, also the exposed tab, rated for 30 V drain-source voltage and 100 A continuous drain current at Tc=25°C.
3 S passive Source terminal, rated for 100 A continuous source current through the body diode at Tc=25°C.

CAD (KiCad official)

  • Symbol: HYG030N03LQ1B
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263-2L (KiCad packages3D, STEP)
  • 3D model files: hyg030n03lq1b-etched.step / hyg030n03lq1b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hyg030n03lq1b.step / hyg030n03lq1b.glb are the bare package body.

Provenance

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

  • Datasheet: HUAYI datasheet (10 pp, sha256 f1efee81589b48ca, retrieved 2026-11-02, tier: lcsc)
  • 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
