DTC114YUA

Changjiang Electronics Tech CJ · Digital Transistors · SOT-323

DTC114YUA from Changjiang Electronics Tech CJ, 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 Base input of the NPN digital transistor with built-in bias resistors, rated for an input voltage VIN of -6 V to +40 V, with VI(off) max 0.3 V at VCC=5 V, IO=100 µA and VI(on) min 1.4 V at VO=0.3 V, IO=1 mA.
2 GND power_in Ground pin as shown in the pin connection diagram; the datasheet gives no separate electrical limit for this pin.
3 OUT output Collector output of the digital transistor, limited to an output current IO of 70 mA and a peak collector current ICM of 100 mA, with VO(on) max 0.3 V at IO/II=5 mA/0.25 mA and supply VCC up to 50 V.
