DTA144EETL

ROHM Semicon · Digital Transistors · SOT-416

DTA144EETL 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 PNP digital transistor; supply voltage VCC is rated at -50V and collector current IC(MAX) at -100mA.
2 IN (BASE) input Input (base) through built-in R1 = 47kΩ, with input voltage rated -40 to 10 V, VI(off) max -0.5V and VI(on) min -3.0V.
3 OUT (COLLECTOR) output Output (collector) terminal with output current rated -30mA and IO(off) max -500nA at VCC = -50V.

CAD (KiCad official)

  • Symbol: DTA144EETL
  • 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: dta144eetl-etched.step / dta144eetl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta144eetl.step / dta144eetl.glb are the bare package body.
