CMUT2907A TR PBFREE

Central Semicon · Bipolar (BJT) · SOT-523

CMUT2907A TR PBFREE from Central Semicon, 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 Base input Base lead of the PNP transistor, with VBE(SAT) of 1.3 V at IC=150 mA, IB=15 mA and 2.6 V at IC=500 mA, IB=50 mA.
2 Emitter passive Emitter lead of the PNP transistor, with an emitter-base breakdown BVEBO of 5.0 V minimum at IE=10 µA and a maximum VEBO rating of 5.0 V.
3 Collector passive Collector lead of the PNP transistor, rated for 60 V VCBO and VCEO, 600 mA continuous collector current and 250 mW power dissipation.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

CAD (KiCad official)

  • Symbol: CMUT2907A TR PBFREE
  • 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: cmut2907a-tr-pbfree-etched.step / cmut2907a-tr-pbfree-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmut2907a-tr-pbfree.step / cmut2907a-tr-pbfree.glb are the bare package body.
