LMBT3906N3T5G

LRC · Bipolar (BJT) · SOT-883

LMBT3906N3T5G from LRC, in a SOT-883. 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 terminal of the PNP general-purpose transistor; it is the control input that drives the device.
2 EMITTER passive Emitter terminal of the PNP general-purpose transistor (LMBT3906N3T5G, marking 2A).
3 COLLECTOR passive Collector terminal of the PNP general-purpose transistor; the datasheet rates collector-emitter voltage at -40 Vdc and collector current at -200 mAdc continuous.

Key specifications

Parameter Value
Manufacturer LRC
Package SOT-883
Category Transistors/Thyristors
Pins 3

CAD (KiCad official)

  • Symbol: LMBT3906N3T5G
  • Footprint: Package_TO_SOT_SMD:SOT-883
  • 3D model: SOT-883, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT 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: lmbt3906n3t5g-etched.step / lmbt3906n3t5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmbt3906n3t5g.step / lmbt3906n3t5g.glb are the bare package body.
