DTC124EUA

TECH PUBLIC · Digital Transistors · SOT-323

DTC124EUA from TECH PUBLIC, 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 (BASE) input Base input through built-in 22kΩ series resistor R1 (with 22kΩ R2 to GND); input voltage rated -10 to +40 V, VI(OFF) min 0.5 V, VI(ON) max 3 V.
2 GND (EMITTER) power_in Emitter/ground terminal of the NPN digital transistor, also the return for the R2 22kΩ base-emitter resistor.
3 OUT (COLLECTOR) output Collector output of the digital transistor, rated 50 V supply (VCC), 30 mA output current (IO) and 100 mA max collector current.
