DDTC144GCA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTC144GCA-7-F from Diodes Incorporated, 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 B passive Base terminal with a built-in R2 bleeder resistor (47kΩ nominal, ±30%) to the emitter; emitter-base voltage is limited to 5 V.
2 E passive Emitter terminal of the NPN pre-biased transistor, with a maximum emitter-base voltage of 5 V.
3 C passive Collector terminal rated for 50 V collector-emitter and collector-base voltage and 100 mA maximum collector current.
