DCX114EUQ-7-F

Overview

The DCX114EUQ-7-F is a complementary pre-biased transistor array manufactured by Diodes Incorporated. It integrates one NPN and one PNP transistor within a single SOT363 surface-mount package. The device features nominal base resistors (R1) of 10 kΩ and emitter resistors (R2) of 10 kΩ for both polarities. It supports a supply voltage (VO) of 50 V, with a maximum collector current of 100 mA and power dissipation of 200 mW. The component operates across a temperature range from -55°C to +150°C.

Feature Summary

• Complementary dual configuration integrating NPN and PNP transistors in a compact SOT363 package
• Integrated biasing network with 10 kΩ input and emitter resistors for simplified circuit design
• Qualified for automotive applications under AEC-Q101 standards and IATF 16949 manufacturing requirements

Applications

• Automotive electronic systems requiring specific change control protocols
• General-purpose switching and logic interface circuits
• Driver stages for low-power loads in industrial equipment

Procurement Notes

Verify the current production status before initiating procurement. The datasheet explicitly lists this part number as NRND (Not Recommended for New Design). Confirm if the manufacturer has issued a formal replacement recommendation or end-of-life notification prior to placing orders.

Selection Notes

Select this component only if the specific 10kΩ/10kΩ resistor ratio matches the circuit requirements. Note that the Q suffix indicates automotive qualification; verify if standard commercial grade parts are sufficient. Ensure the SOT363 footprint aligns with the PCB layout constraints.

Part Context

This component belongs to the DCX114 series of complementary pre-biased transistors. It shares the same internal schematic and electrical characteristics as the non-automotive qualified DCX114EU-7-F variant. The primary distinction lies in the manufacturing facility certification and adherence to automotive quality standards.

Replacement Considerations

The datasheet recommends using ACX114EUQ as the direct replacement for this NRND part number. Verify pinout compatibility and electrical specifications between the legacy DCX114EUQ-7-F and the suggested ACX114EUQ substitute.
