NTK3043NT1G

onsemi · MOSFETs · SOT-723

NTK3043NT1G from onsemi, in a SOT-723. 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 of the N-channel MOSFET; the gate-to-source voltage is rated at VGS = 10 V maximum.
2 Source passive Source terminal of the MOSFET; source (body diode) current IS is rated at 286 mA maximum.
3 Drain passive Drain terminal of the MOSFET; drain-to-source voltage is rated at VDSS = 20 V, with continuous drain current ID of 255 mA at TA = 25C steady state (285 mA for t ≤ 5 s).

CAD (KiCad official)

  • Symbol: NTK3043NT1G
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 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: ntk3043nt1g-etched.step / ntk3043nt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ntk3043nt1g.step / ntk3043nt1g.glb are the bare package body.
