BCX5110TA

Diodes Incorporated · Bipolar (BJT) · SOT-89

BCX5110TA from Diodes Incorporated, in a SOT-89. 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 B input Base of the PNP transistor; the datasheet gives IB = -100 mA continuous and IBM = -200 mA peak pulse, with VEBO of -5 V.
2 C passive Collector of the PNP transistor, also the exposed collector tab used as the heat-sinking pad; the datasheet gives IC = -1 A continuous, ICM = -2 A peak, and VCEO of -45 V for the BCX51 family.
3 E passive Emitter of the PNP transistor; the datasheet gives a maximum emitter-base voltage VEBO of -5 V.

Materials and finish

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

Part Material Colour / plating Datasheet says Page
contacts tin • Terminals: Matte Tin Finish Leads; Solderable per MIL-STD-202 Method 208 1

CAD (KiCad official)

  • Symbol: BCX5110TA
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: bcx5110ta-etched.step / bcx5110ta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcx5110ta.step / bcx5110ta.glb are the bare package body.
