DCX144EUQ-7-F

Overview

The DCX144EUQ-7-F is a complementary pre-biased transistor array manufactured by Diodes Incorporated. It integrates one NPN and one PNP bipolar junction transistor within a single SOT-363 surface-mount package. The device features an internal bias resistor network with nominal values of 47 kΩ for both R1 and R2. Key electrical specifications include a maximum supply voltage (VO) of 50 V, a continuous collector current (IO) of ±100 mA, and a power dissipation (PD) of 200 mW. The component is qualified to AEC-Q101 standards for automotive applications and operates across a temperature range of -55°C to +150°C.

Feature Summary

• Complementary dual configuration integrating matched NPN and PNP transistors in a compact SOT-363 package
• Integrated base and emitter bias resistors (47 kΩ each) simplify circuit design and reduce board space
• AEC-Q101 qualified and PPAP capable for use in automotive electronics manufacturing environments
• Lead-free and fully RoHS compliant construction utilizing halogen-free green molding compounds

Applications

• Automotive logic level shifting and signal switching circuits
• General-purpose digital switching and interface buffering
• Power management control stages requiring complementary drive signals

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the selected variant meets all required automotive qualification standards and packaging specifications. Ensure compatibility with automated assembly processes and verify compliance with regional environmental directives such as RoHS and REACH restrictions.

Selection Notes

Select this component when a matched NPN/PNP pair with integrated biasing is required in a minimal footprint. The 47 kΩ resistor values are suitable for standard logic interfacing. Consider the 200 mW total power dissipation limit and thermal resistance characteristics during layout planning to ensure reliable operation under maximum load conditions.

Part Context

This part belongs to the DCX series of complementary pre-biased transistors from Diodes Incorporated. The 'UQ' designation indicates it is an automotive-grade version manufactured in IATF 16949 certified facilities. It shares the same physical package and basic electrical parameters as the standard DCX144EU but includes additional quality controls for automotive supply chains.

Replacement Considerations

The datasheet explicitly recommends using the ACX124EUQ as a replacement for discontinued NRND parts in the DCX family. Verify pinout compatibility and electrical parameter equivalence before substituting with other manufacturers' SOT-363 complementary arrays.
