DTA123YETL

ROHM Semicon · Digital Transistors · SOT-416

DTA123YETL 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 (EMITTER) power_in Ground (+) / emitter terminal of the built-in PNP transistor, the common return for the input and output.
2 IN (BASE) input Input (base) through built-in R1 = 2.2kΩ, with R2 = 10kΩ to the emitter; input voltage range -12 to 5 V, VI(off) max -0.3 V, VI(on) min -3.0 V.
3 OUT (COLLECTOR) output Output (collector) of the built-in PNP transistor, rated to -100 mA output current and -50 V supply voltage.

CAD (KiCad official)

  • Symbol: DTA123YETL
  • 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: dta123yetl-etched.step / dta123yetl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta123yetl.step / dta123yetl.glb are the bare package body.
