2KK5016

KEXIN · MOSFETs · SOT-523

2KK5016 from KEXIN, 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 of the N-channel MOSFET, rated for VGS of ±10 V and with an ESD-protected gate.
2 Source passive Source terminal of the N-channel MOSFET, to which VGS is referenced.
3 Drain passive Drain terminal of the N-channel MOSFET, rated for VDS of 20 V and continuous ID of 238 mA at TA = 25°C (steady state, on FR4 with 1 in² pad).

CAD (KiCad official)

  • Symbol: 2KK5016
  • 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: 2kk5016-etched.step / 2kk5016-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2kk5016.step / 2kk5016.glb are the bare package body.
