Changjing · MOSFETs · SOT-523

2SK3019 from Changjing, 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 GATE input Gate terminal; gate-source voltage is rated ±20 V (VGS) and gate threshold VGS(th) is 0.8 V min to 1.5 V typ at VDS = 3 V, ID = 100 µA.
2 SOURCE passive Source terminal; the reference for the ±20 V gate-source rating and the return path for drain current, with a continuous drain current rating of 0.1 A.
3 DRAIN passive Drain terminal; drain-source voltage is rated 30 V (V(BR)DSS minimum 30 V) and total power dissipation is 0.15 W.

CAD (KiCad official)

  • Symbol: 2SK3019
  • 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: 2sk3019-etched.step / 2sk3019-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sk3019.step / 2sk3019.glb are the bare package body.
