DTA144EKA

Foshan Blue Rocket Elec · Digital Transistors · SOT-23

DTA144EKA 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 transistor, which connects to the built-in bias resistor network (R1 typ. 47 kΩ, range 32.9-61.1 kΩ; R2/R1 ratio 1.0, range 0.8-1.2) and has an input voltage rating VIN of 10 V in the absolute maximum table.
2 Emitter passive Emitter terminal of the PNP digital transistor; the device absolute maximum ratings apply, with output current IC(max) of -100 mA and power dissipation Pd of 200 mW.
3 Collector passive Collector output terminal of the PNP digital transistor, rated for output voltage VCC of -50 V and output current IC(max) of -100 mA in the absolute maximum ratings.
