DTC114EKA

Foshan Blue Rocket Elec · Digital Transistors · SOT-23

DTC114EKA from Foshan Blue Rocket Elec, in a SOT-23. 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 Base input Base pin of the built-in bias-resistor NPN digital transistor; the datasheet gives VI(on) of 3 V minimum (VO=0.3 V, IO=10 mA) and VI(off) of 0.5 V maximum (VCC=5.0 V, IO=100 µA), with input resistor R1 of 10 kΩ typical (7 to 13 kΩ).
2 Emitter passive Emitter pin of the NPN digital transistor; the absolute maximum input voltage VIN is -10 V, referenced to this terminal.
3 Collector passive Collector (output) pin; absolute maximum ratings are output voltage VCC 50 V, output current IO 50 mA (ICM 100 mA), and collector dissipation PC 200 mW.
