DCX114YUQ-7-F

Overview

The DCX114YUQ-7-F is a complementary pre-biased transistor array manufactured by Diodes Incorporated, housed in an SOT363 surface-mount package. It integrates one NPN and one PNP bipolar junction transistor with built-in bias resistors (R1 = 10 kΩ, R2 = 47 kΩ). The device supports a supply voltage of 50 V and offers a peak collector current of 100 mA with a power dissipation rating of 200 mW. It features a minimum DC current gain of 80 and a transition frequency of 250 MHz. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Complementary dual configuration integrating NPN and PNP transistors within a single compact SOT363 package.
• Built-in bias resistor network simplifies circuit design by eliminating external base drive components.
• Qualified for automotive applications under AEC-Q101 standards with PPAP capability.
• Manufactured in IATF 16949 certified facilities ensuring specific change control compliance.

Applications

• Automotive logic switching circuits requiring high reliability and specific change control protocols.
• General-purpose digital buffering and level shifting in consumer electronics.
• Driver stages for low-power loads in industrial control systems.

Procurement Notes

Verify the component status before procurement as the datasheet lists this part number as Not Recommended for New Design (NRND). Confirm that the 'Q' suffix denotes AEC-Q101 qualification and IATF 16949 manufacturing origin if automotive compliance is required. Ensure the ordering quantity matches the specified reel size of 3,000 units per carrier.

Selection Notes

Select this component when a complementary pair with asymmetric bias ratios is needed for push-pull or differential configurations. The 10 kΩ input resistor provides moderate drive current requirements, while the 47 kΩ emitter resistor ensures stable cutoff. Verify that the 50V breakdown voltage and 100mA current limits align with the target application's electrical stress conditions.

Part Context

This device belongs to the DCX114 series of complementary pre-biased transistors. It shares the same internal schematic and electrical characteristics as the DCX114YU-7-F but includes the 'Q' suffix to indicate automotive-grade qualification. Both parts utilize the standard SOT363 footprint and marking code C14.

Replacement Considerations

The datasheet explicitly recommends using ACX114YUQ as the replacement for this NRND part number. Verify pin compatibility and electrical equivalence between the legacy DCX series and the newer ACX series before substitution.
