DCX144EU-7-F

Overview

The DCX144EU-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 SOT363 surface-mount package. The device features built-in biasing resistors, each with a nominal value of 47 kΩ. It supports a supply voltage of 50 V and handles a continuous collector current of 100 mA per element. The unit provides a gain-bandwidth product of 250 MHz and dissipates up to 200 mW of power. It operates reliably across a temperature range from -55°C to +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors with internal biasing resistors in a compact SOT363 package
• Designed for automated assembly using lead-free, halogen-free, and antimony-free materials
• Suitable for automotive applications requiring specific change control, meeting AEC-Q101 qualification standards

Applications

• Automotive electronic systems requiring qualified components
• General-purpose switching and logic interface circuits
• Driver stages for low-power loads

Procurement Notes

Verify the component status as Active before procurement. Confirm that the ordering suffix matches the required packaging format, such as the standard 3,000-unit reel or the cut tape variant. Ensure compliance with RoHS directives and confirm suitability for any specific automotive quality requirements if applicable to the design.

Selection Notes

Select this part when a complementary pair with integrated base resistors is needed to simplify circuit layout. The 47 kΩ resistor values are suitable for standard logic interfacing. Consider the SOT363 footprint constraints and verify thermal dissipation limits relative to the ambient operating conditions of the final application.

Part Context

This component belongs to the DCX (XXXX) U series of 50V complementary pre-biased transistors. The series includes various configurations with different resistor ratios and polarities, all housed in the SOT363 package. The 'Q' suffix variants indicate AEC-Q101 qualification for automotive use, while the standard EU suffix denotes general industrial or consumer electronics applications.

Replacement Considerations

Direct substitutes include the DCX144EU-7R-F for alternative packaging. For automotive-grade requirements, the DCX144EUQ-7-F is the appropriate equivalent. Designers should verify pin compatibility and electrical characteristics against these alternatives.
