FMMT493

hongjiacheng · Bipolar (BJT) · SOT-23

FMMT493 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 input Base terminal of the NPN transistor; the datasheet gives VBE(sat) max 1.15 V at IC=1000mA, IB=100mA.
2 E passive Emitter terminal of the NPN transistor; the emitter-base breakdown voltage V(BR)EBO is at least 5.0 V at IE=100μA.
3 C passive Collector terminal of the NPN transistor; rated for VCBO 120 V, VCEO 100 V and collector current IC 1.0 A.

CAD (KiCad official)

  • Symbol: FMMT493
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fmmt493-etched.step / fmmt493-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fmmt493.step / fmmt493.glb are the bare package body.
