DCX144EUQ-7R-F

Overview

The DCX144EUQ-7R-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 nominal base resistors of 47 kΩ for both the NPN and PNP sections, facilitating direct interface with logic outputs. It supports a supply voltage of 50 V and delivers a continuous collector current of 100 mA per element. The component is qualified to AEC-Q101 standards for automotive applications and operates across an extended temperature range from -55°C to +150°C.

Feature Summary

• Complementary dual configuration integrating NPN and PNP transistors in a compact SOT-363 package
• Pre-biased design with integrated 47 kΩ base resistors for simplified circuit interfacing
• AEC-Q101 qualification and PPAP capability for automotive-grade reliability requirements

Applications

• Automotive digital switching circuits requiring specific change control protocols
• General-purpose logic level translation between microcontrollers and loads
• Driver stages for relays, solenoids, or LED indicators in industrial systems

Procurement Notes

Verify the complete part number including the suffix against official distributor catalogs before ordering. Confirm that the specific reel size and tape width match your automated assembly equipment specifications. Ensure compliance with RoHS and halogen-free material definitions required by your manufacturing facility. Cross-reference the manufacturer's latest datasheet revision to validate any potential updates to mechanical dimensions or electrical characteristics prior to final procurement.

Selection Notes

Select this component when a matched NPN/PNP pair with identical 47 kΩ biasing is required in a minimal footprint. The SOT-363 package is suitable for high-density PCB layouts where space is constrained. Consider the 50 V breakdown voltage and 100 mA current rating to ensure adequate headroom for the intended load conditions. Verify thermal dissipation requirements against the specified power derating curve for the operating environment.

Part Context

This part belongs to the DCX144 series of complementary pre-biased transistors. It shares the same internal schematic and electrical parameters as the DCX144EUQ-7-F variant but utilizes a different packaging designation indicated by the '7R' suffix. Both variants are listed as active components in the manufacturer's portfolio and utilize the C20 marking code on the SOT-363 package.

Replacement Considerations

The DCX144EUQ-7-F is a confirmed substitute with identical electrical characteristics and pinout. For designs originally using NRND parts, the ACX124EUQ may serve as a functional alternative for lower resistor value requirements, though it differs electrically from the DCX144 series.
