DTC043TMT2L

ROHM Semicon · Digital Transistors · SOT-723

DTC043TMT2L from ROHM Semicon, in a SOT-723. 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 BASE input Base input through built-in R1 = 4.7kΩ (3.29 to 6.11kΩ) in series, so no external input resistor is needed; VEBO max 5V.
2 EMITTER passive Emitter terminal of the NPN transistor, normally tied to ground; VEBO rating 5V.
3 COLLECTOR passive Collector terminal of the NPN transistor, rated VCEO 50V, VCBO 50V and IC 100mA.

CAD (KiCad official)

  • Symbol: DTC043TMT2L
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: dtc043tmt2l-etched.step / dtc043tmt2l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc043tmt2l.step / dtc043tmt2l.glb are the bare package body.
