DTC123JE

HXY MOSFET · Digital Transistors · SOT-523

DTC123JE from HXY MOSFET, 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 terminal of the built-in bias-resistor inverter, with an input voltage rating of -10 to +40 V, VI(off) of 0.5 V max at VCC=5V and IO=100µA, and VI(on) of 1.1 V at VO=0.3V and IO=5mA.
2 GND power_in Ground reference pin; the datasheet gives no separate voltage or current limit for this pin.
3 OUT output Output terminal with an output current rating of 100 mA, VO(on) of 0.1 to 0.3 V at IO/II=5mA/0.25mA, and IO(off) of 0.5 µA max at VCC=50V and VI=0.

CAD (KiCad official)

  • Symbol: DTC123JE
  • 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: dtc123je-etched.step / dtc123je-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc123je.step / dtc123je.glb are the bare package body.
