MMBTA44

hongjiacheng · Bipolar (BJT) · SOT-23

MMBTA44 from hongjiacheng, in a SOT-23. 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 passive Base terminal of the NPN transistor; the emitter-base breakdown voltage V(BR)EBO is 6.0 V minimum at IE=10μA, and the emitter-base cut-off test uses VEB=4.0V.
2 E passive Emitter terminal of the NPN transistor; the absolute maximum emitter-base voltage VEBO is 6.0 V, with collector current limited to 0.2 A.
3 C passive Collector terminal of the NPN transistor; limited to a collector-base voltage VCBO of 400 V, a collector-emitter voltage VCEO of 400 V, a collector current IC of 0.2 A, and a collector power dissipation PC of 350 mW.

CAD (KiCad official)

  • Symbol: MMBTA44
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbta44-etched.step / mmbta44-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbta44.step / mmbta44.glb are the bare package body.
