CB2301T-2.8A

CBI · MOSFETs · SOT-523

CB2301T-2.8A from CBI, 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 of the P-channel MOSFET, rated for a gate-source voltage VGS of ±8 V.
2 SOURCE passive Source of the P-channel MOSFET, with a continuous source-drain diode current IS rated at -0.72 A in the maximum ratings.
3 DRAIN passive Drain of the P-channel MOSFET, rated for a drain-source voltage VDS of -20 V and a continuous drain current ID of -2.8 A.

CAD (KiCad official)

  • Symbol: CB2301T-2.8A
  • 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: cb2301t-2-8a-etched.step / cb2301t-2-8a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cb2301t-2-8a.step / cb2301t-2-8a.glb are the bare package body.
