DCX123JUQ-7-F

Diodes Incorporated · Digital Transistors · SOT-363

DCX123JUQ-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 / COM1 passive Emitter (COM1) of transistor Q1 in the built-in R1 2.2kΩ / R2 47kΩ bias network.
2 B1 / IN1 input Base input (IN1) of Q1 through the 2.2kΩ series resistor R1; the 47kΩ R2 is connected between base and emitter.
3 C2 / OUT2 output Collector output (OUT2) of transistor Q2; output voltage rating VO is 50V.
4 E2 / COM2 passive Emitter (COM2) of transistor Q2 in the built-in R1 2.2kΩ / R2 47kΩ bias network.
5 B2 / IN2 input Base input (IN2) of Q2 through the 2.2kΩ series resistor R1; the 47kΩ R2 is connected between base and emitter.
6 C1 / OUT1 output Collector output (OUT1) of transistor Q1; output voltage rating VO is 50V.
