DDA114YU-7-F

Diodes Incorporated · Digital Transistors · SOT-363

DDA114YU-7-F from Diodes Incorporated, in a SOT-363. 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 E1 passive Emitter of the first PNP transistor (Q1); the absolute maximum supply voltage between pins 1 and 6 is -50 V.
2 B1 input Base (input) of Q1 with built-in input resistor R1 (10 kΩ, NOM) for DDA114YU; input voltage between pins 1 and 2 is limited to +6 V to -40 V.
3 C2 passive Collector of the second PNP transistor (Q2); the absolute maximum supply voltage between pins 4 and 3 is -50 V.
4 E2 passive Emitter of Q2; it is the reference terminal for the supply voltage and input voltage between pins 4 and 3 and pins 4 and 5.
5 B2 input Base (input) of Q2 with built-in input resistor R1 (10 kΩ, NOM) for DDA114YU; input voltage between pins 4 and 5 is limited to +6 V to -40 V.
6 C1 passive Collector of Q1 (output); the absolute maximum output current for DDA114YU is -70 mA and the supply voltage between pins 1 and 6 is -50 V.
