DCX123JU-7-F

Overview

The DCX123JU-7-F is a complementary pre-biased transistor array manufactured by Diodes Incorporated, featuring integrated NPN and PNP sections within a single SOT-363 package. It operates with a supply voltage of 50V and supports continuous collector currents up to 100mA for both polarities. The device incorporates nominal bias resistors of R1 = 2.2kΩ and R2 = 47kΩ, yielding a resistance ratio of approximately 0.046. Designed for surface-mount assembly, it provides a total power dissipation of 200mW and functions reliably across an operating temperature range from -55°C to +150°C.

Feature Summary

• Complementary dual configuration integrating one NPN and one PNP transistor in a compact SOT-363 package
• Integrated base biasing network eliminates external resistor requirements for simplified circuit design
• Automotive-grade qualification available through the AEC-Q101 standard for specific change control applications

Applications

• General-purpose switching circuits requiring complementary logic levels
• Driver stages for low-power loads in industrial control systems
• Signal level translation between different voltage domains

Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm RoHS compliance status and ensure the ordering suffix matches the required packaging quantity. Cross-reference the date code to validate production timelines and confirm availability through authorized distribution channels prior to finalizing procurement orders.

Selection Notes

Select this component when a matched NPN/PNP pair with fixed internal biasing is required to minimize board space. Ensure the 50V breakdown voltage and 100mA current limits align with the target application's electrical demands. Verify that the 2.2kΩ input resistor value provides appropriate drive current for the connected logic source without exceeding maximum ratings.

Part Context

This part belongs to the DCX series of complementary pre-biased transistors produced by Diodes Incorporated. It shares the SOT-363 footprint with other variants like the DCX124EU but differs in internal resistor values and polarity configurations. The series is designed to replace discrete transistor networks, offering improved consistency and reduced assembly complexity for digital switching applications.

Replacement Considerations

The datasheet identifies the ACX124EUQ as a replacement for the NRND DCX124EUQ variant. No direct substitute is listed for the DCX123JU-7-F; verify pin compatibility and electrical parameters before considering alternative manufacturers.
