DTA143XETL

ROHM Semicon · Digital Transistors · SOT-416

DTA143XETL from ROHM Semicon, in a SOT-416. 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 GND power_in GND (+) / emitter of the built-in PNP transistor, connected to the R2 return and the common reference of the inverter.
2 IN input Input (base) through built-in R1 = 4.7kΩ with R2 = 10kΩ to emitter; VI(off) max -0.3V, VI(on) min -2.5V, input voltage rating -20 to 7V.
3 OUT output Output (collector) rated for -50V supply (VCC) and -100mA output current, with VO(on) max -300mV at IO = -10mA.

CAD (KiCad official)

  • Symbol: DTA143XETL
  • Footprint: Package_TO_SOT_SMD:SOT-416
  • 3D model: SOT-416, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 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: dta143xetl-etched.step / dta143xetl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143xetl.step / dta143xetl.glb are the bare package body.
