DTA123JETL

ROHM Semicon · Digital Transistors · SOT-416

DTA123JETL 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, which is the common reference with R2 connected to the input side.
2 IN input Input (base) through built-in 2.2kΩ R1, with input voltage rated -12 to 5 V, VI(off) max -0.5 V, VI(on) min -1.1 V and input current max -3.6 mA.
3 OUT output Output (collector) rated for supply voltage VCC of -50 V and output current IO of -100 mA.

CAD (KiCad official)

  • Symbol: DTA123JETL
  • 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: dta123jetl-etched.step / dta123jetl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta123jetl.step / dta123jetl.glb are the bare package body.
