AD-DTC114YUA

Changjing · Digital Transistors · SOT-323

AD-DTC114YUA 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 connected through built-in R1 (7 to 13 kΩ) to the transistor base; VI(off) min 0.3 V, VI(on) max 1.4 V, input voltage range -6 to 40 V.
2 GND power_in Ground, connected to the transistor emitter and the R2 resistor.
3 OUT output Open-collector output (transistor collector) with output current up to 70 mA and supply voltage up to 50 V.
