DDTA114YCA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTA114YCA-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 IN input Base input of the built-in bias network; the input voltage is limited to +6 V to -40 V (pin 1 to pin 2) per the maximum ratings for DDTA114YCA.
2 GND power_in Common ground reference for the input voltage and supply, with the supply rated at VCC = -50 V maximum (pin 3 to pin 2).
3 OUT output Collector output of the pre-biased PNP transistor, rated for an output current of -70 mA maximum for DDTA114YCA (-100 mA absolute maximum for IC).
