DCX123JUQ-7-F

Overview

The DCX123JUQ-7-F is a complementary pre-biased transistor pair featuring an NPN and PNP section within a single SOT-363 package. It operates with a supply voltage of 50V and includes built-in biasing resistors (R1: 2.2kΩ, R2: 47kΩ). The device supports continuous collector currents up to 100mA for both polarities and dissipates 200mW of power. Designed for surface-mount assembly, it offers high DC current gain and low saturation voltages. The component is AEC-Q101 qualified for automotive applications.

Feature Summary

• Complementary NPN/PNP configuration in a compact SOT-363 package
• Built-in biasing resistors simplify circuit design and reduce board space
• AEC-Q101 qualified for automotive reliability and IATF 16949 manufacturing
• Totally lead-free and fully RoHS compliant

Applications

• Automotive logic level shifting and switching circuits
• General-purpose digital switching applications requiring complementary outputs
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific 'UQ' suffix designation against the manufacturer's latest documentation to confirm automotive qualification status and change control requirements. Ensure compatibility with AEC-Q101 standards if deploying in automotive environments. Confirm packaging details such as reel size and tape width match automated assembly equipment specifications before finalizing orders.

Selection Notes

Select this component when a matched NPN/PNP pair with integrated biasing is required in a minimal footprint. The 2.2kΩ input resistor value suits moderate drive current applications. Verify that the 50V breakdown voltage meets system requirements. Consider thermal derating curves if operating near maximum power dissipation limits in enclosed spaces.

Part Context

This part belongs to the DCX series of complementary pre-biased transistors from Diodes Incorporated. It shares the SOT-363 form factor with other variants like DCX123JU but differs in resistance values and automotive qualification. The 'Q' suffix typically denotes enhanced quality or automotive-grade processing compared to standard commercial versions.

Replacement Considerations

Direct substitutes include DCX123JU-7-F for non-automotive applications. For automotive replacements, verify ACX series equivalents if available. Ensure pinout compatibility and electrical parameters match before substitution.
