DTA114EKA

Foshan Blue Rocket Elec · Digital Transistors · SOT-23

DTA114EKA 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 input of the PNP digital transistor with built-in bias resistor R1 (10 kΩ typical, 7 to 13 kΩ), where VI(off) is at most -0.5 V and VI(on) at most -3 V.
2 Emitter passive Emitter terminal of the PNP transistor, with collector current IC limited to -100 mA absolute maximum.
3 Collector output Collector output terminal, with output voltage VCC limited to -50 V and output current IC limited to -100 mA absolute maximum.
