DTC143EMT2L

ROHM Semicon · Digital Transistors · SOT-723

DTC143EMT2L 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 IN (BASE) input Base input through built-in R1 = 4.7kΩ, with VI(off) max 0.5V at VCC = 5V and VI(on) min 3.0V, input voltage range -10 to 30V.
2 GND (EMITTER) power_in Ground/emitter terminal, connected to the base through built-in R2 = 4.7kΩ.
3 OUT (COLLECTOR) output Open-collector output, rated VCC 50V and output current up to 100mA, with VO(on) max 300mV at IO = 10mA.

CAD (KiCad official)

  • Symbol: DTC143EMT2L
  • 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: dtc143emt2l-etched.step / dtc143emt2l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143emt2l.step / dtc143emt2l.glb are the bare package body.
