DTC124EE

CBI · Digital Transistors · SOT-523

DTC124EE from CBI, in a SOT-523. 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 IN input Input through built-in R1 (22 kΩ typ) to the NPN base; input voltage range -10 to +40 V, VI(off) 0.5 V max and VI(on) 3 V min.
2 GND power_in Ground, connected to the emitter and to R2 of the built-in bias network.
3 OUT output Open-collector output of the NPN transistor; output current 30 mA max (IO), 100 mA peak, supply voltage 50 V max.

CAD (KiCad official)

  • Symbol: DTC124EE
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, 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: dtc124ee-etched.step / dtc124ee-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc124ee.step / dtc124ee.glb are the bare package body.
