DDA123JU-7-F

Diodes Incorporated · Digital Transistors · SOT-363

DDA123JU-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 pre-biased transistor (reference for VCC of -50 V to pin 6 and for input voltage to pin 2).
2 B1 input Input (base through R1 = 2.2kΩ) of the first transistor, with input voltage rated +5 V to -12 V relative to pin 1.
3 C2 output Output (collector) of the second transistor, with supply voltage rated -50 V relative to pin 4 and output current up to -100 mA.
4 E2 passive Emitter of the second PNP pre-biased transistor (reference for VCC of -50 V to pin 3 and for input voltage to pin 5).
5 B2 input Input (base through R1 = 2.2kΩ) of the second transistor, with input voltage rated +5 V to -12 V relative to pin 4.
6 C1 output Output (collector) of the first transistor, with supply voltage rated -50 V relative to pin 1 and output current up to -100 mA.
