DCX123JU-7

Overview

The DCX123JU-7-F is a complementary pre-biased transistor pair in an SOT-363 package, manufactured by Diodes Incorporated. It integrates one NPN and one PNP transistor with built-in biasing resistors (R1=2.2kΩ, R2=47kΩ). The device supports a supply voltage of 50V, continuous collector current of 100mA, and peak current of 100mA. Power dissipation is rated at 200mW, with an operating temperature range from -55°C to +150°C. It features a minimum DC current gain of 80 and complies with RoHS standards.

Feature Summary

• Complementary NPN/PNP configuration with integrated biasing resistors
• Surface-mount SOT-363 package optimized for automated assembly
• Halogen-free and antimony-free green device compliant with environmental directives

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Confirm that the component status is listed as Active rather than Not Recommended for New Design (NRND). Ensure compliance with required environmental specifications such as RoHS and halogen-free requirements. Check for any applicable automotive qualification standards if the application demands AEC-Q101 certification.

Selection Notes

Select this component when a compact dual-transistor solution with fixed biasing is required. Verify that the 2.2kΩ input resistor value aligns with the driving circuit's current capabilities. Ensure the 50V voltage rating and 100mA current limits exceed the maximum expected operational stresses. Consider the thermal resistance characteristics for power dissipation management in the final enclosure design.

Part Context

This part belongs to the DCX series of 50V complementary pre-biased transistors. It shares the same physical SOT-363 footprint and internal structure as other variants in the family, differing primarily in the nominal values of the integrated biasing resistors. This specific model provides a 2.2kΩ base resistor for both the NPN and PNP sections.

Replacement Considerations

Publicly confirmed substitutes include the DCX123JUQ-7-F variant within the same product line. Other models in the DCX series may serve as functional alternatives if their specific resistor ratios match the circuit requirements.
