BRDTC114EKAQ

Foshan Blue Rocket Elec · Digital Transistors · SOT-23

BRDTC114EKAQ 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 is the input of the built-in bias-resistor digital transistor, with R1 specified at 10 kΩ typical (7 kΩ min, 13 kΩ max) and an input current II of 0.88 mA at VI = 5.0 V.
2 Emitter passive Emitter is the transistor emitter terminal; the datasheet gives no separate voltage or current limit for this pin and lists only the device-level absolute maximum ratings.
3 Collector passive Collector is the output terminal, rated at a supply/output voltage VCC of 50 V, output current IO of 50 mA (ICM 100 mA peak), and collector dissipation PC of 200 mW.
