DDTA115TCA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTA115TCA-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 input Base input of the PNP pre-biased transistor, driven through the built-in series resistor R1 of 100kΩ nominal (±30% tolerance), with emitter-base voltage limited to -5 V.
2 E passive Emitter terminal of the PNP transistor, with emitter-base breakdown voltage rated at -5 V minimum.
3 C passive Collector terminal of the PNP transistor, rated for -50 V collector-base and collector-emitter voltage and -100 mA maximum collector current.
