DTC143XETL

ROHM Semicon · Digital Transistors · SOT-416

DTC143XETL 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 of the built-in NPN transistor, tied to the bottom of R2 (R2 = 10kΩ typ.).
2 IN (BASE) input Input / base connected through built-in R1 (4.7kΩ typ.); VIN rated -7 to 20 V, VI(off) max 0.3 V, VI(on) min 2.5 V.
3 OUT (COLLECTOR) output Output / collector of the built-in NPN transistor; VCC max 50 V, output current IO max 100 mA.

CAD (KiCad official)

  • Symbol: DTC143XETL
  • 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: dtc143xetl-etched.step / dtc143xetl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143xetl.step / dtc143xetl.glb are the bare package body.
