FMMT449TA

Diodes Incorporated · Bipolar (BJT) · SOT-23

FMMT449TA from Diodes Incorporated, 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 of the NPN transistor; base current is rated at 200 mA maximum and emitter-base voltage at 5 V maximum.
2 E passive Emitter of the NPN transistor, carrying the continuous collector current of 1 A (2 A peak).
3 C passive Collector of the NPN transistor; VCEO is 30 V and VCBO is 50 V maximum, with 1 A continuous and 2 A peak collector current.

CAD (KiCad official)

  • Symbol: FMMT449TA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fmmt449ta-etched.step / fmmt449ta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fmmt449ta.step / fmmt449ta.glb are the bare package body.
