ES138KR

ElecSuper · MOSFETs · SOT-723

ES138KR from ElecSuper, 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, rated for VGS of ±20 V (absolute maximum), with 10 V and 4.5 V RDS(on) specified.
2 Source passive Source terminal of the N-channel MOSFET, the reference for the gate-source voltage (VGS).
3 Drain passive Drain terminal of the N-channel MOSFET, rated 60 V drain-source breakdown (BVDSS) and 0.25 A continuous drain current.

CAD (KiCad official)

  • Symbol: ES138KR
  • 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: es138kr-etched.step / es138kr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); es138kr.step / es138kr.glb are the bare package body.
