FMMT38CTA

Diodes Incorporated · Darlington Transistors · SOT-23

FMMT38CTA from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Base input Base control terminal rated for maximum emitter-base voltage VEBO of 10V with typical turn-on voltage VBE(ON) of 1.3V at IC = 800mA, VCE = 5V under pulsed conditions.
2 Emitter passive Emitter terminal rated for maximum emitter-base voltage VEBO of 10V with typical cutoff current IEBO of 1 nA at VEB = 8V.
3 Collector passive Collector terminal rated for maximum collector-emitter voltage VCEO of 60V, maximum continuous collector current IC of 300mA, and maximum peak pulse current ICM of 800mA.

CAD (KiCad official)

  • Symbol: FMMT38CTA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fmmt38cta-etched.step / fmmt38cta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fmmt38cta.step / fmmt38cta.glb are the bare package body.
