DCX114EU-7-F

Overview

The DCX114EU-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 nominal base resistors of 10 kΩ for both the NPN and PNP sections, with an emitter resistor ratio of 1:1. Key electrical ratings include a maximum supply voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation capacity of 200 mW. The component operates across a temperature range from -55°C to +150°C.

Feature Summary

• Integrates matched NPN and PNP transistors with internal biasing resistors in a compact dual configuration.
• Designed for automated assembly using a lead-free, halogen-free molded plastic package.
• Provides simplified circuit design by eliminating external biasing components.

Applications

• General-purpose switching applications requiring complementary logic levels.
• Driver circuits for low-power loads utilizing integrated bias networks.
• Automotive electronics compliant with specific change control requirements.

Procurement Notes

Verify the active status and packaging specifications against the manufacturer's official documentation before procurement. Confirm that the SOT363 footprint matches the target PCB layout. Ensure compliance with RoHS and REACH directives as specified in the product data sheet. Check for any recent product change notifications or obsolescence notices directly from Diodes Incorporated.

Selection Notes

Select this component when a complementary pair with equal 10 kΩ base resistance is required. Verify that the 50 V breakdown voltage and 100 mA current limits satisfy the application's peak demands. Consider the thermal resistance characteristics if operating near the upper temperature limits. Compare against other variants in the DCX series if different resistor values are needed.

Part Context

This part belongs to the DCX (XXXX) U family of 50V complementary pre-biased transistors. It shares the SOT363 package form factor with other members like the DCX124EU and DCX144EU, differing primarily in internal resistor configurations. The 'EU' suffix denotes the specific 10kΩ/10kΩ resistor combination within this product line.

Replacement Considerations

The datasheet identifies the DCX114EUQ-7-F as Not Recommended for New Design (NRND), suggesting the ACX114EUQ as a potential alternative. Verify pin compatibility and electrical parameters before substituting with other DCX series parts.
