DTC143EUA

Changjing · Digital Transistors · SOT-323

DTC143EUA from Changjing, in a SOT-323. 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 of the inverter with a built-in input resistor of 4.7 kΩ typical (3.29 kΩ min, 6.11 kΩ max), with input voltage rated from -10 V to +30 V and input current 1.8 mA max at VI = 5 V.
2 GND power_in Ground reference pin for the NPN digital transistor and its built-in bias resistors.
3 OUT output Open-collector NPN output, rated for an output current of 100 mA max and a supply voltage VCC of 50 V max, with VO(on) of 0.3 V max at IO/II = 10 mA / 0.5 mA.
