Overview
The DCX143TU-7-F is a complementary pre-biased transistor pair in an SOT-363 package, featuring one NPN and one PNP element. It integrates a single 4.7 kΩ input resistor (R1) per transistor. Key electrical parameters include a supply voltage of 50 V, collector-emitter breakdown voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device operates within a temperature range of -55°C to +150°C and offers a gain-bandwidth product of 250 MHz.
Feature Summary
- Integrates dual transistors with built-in bias resistors to reduce component count and PCB area.
- Complementary configuration provides matched NPN and PNP switching capabilities.
- Surface-mount SOT-363 package designed for automated assembly processes.
Applications
- General-purpose digital switching circuits
- Driver stages for logic interfaces
- Power management control applications
Procurement Notes
Verify the complete part number including suffixes such as -7-F against official manufacturer documentation before ordering. Confirm that the specific marking code C07 matches your manufacturing requirements. Ensure compliance with RoHS directives and check for any automotive qualification needs if applicable to your design specifications.
Selection Notes
Select this component when a compact solution for simultaneous NPN and PNP switching is required. The integrated 4.7 kΩ resistor simplifies base drive circuitry. Verify that the 100 mA current rating and 50 V voltage limits accommodate your load conditions. Consider thermal derating curves if operating at elevated ambient temperatures.
Part Context
This component belongs to the DCX series of complementary pre-biased transistors manufactured by Diodes Incorporated. It shares the SOT-363 footprint with other variants like the DCX143EU and DCX143ZU, which differ primarily in their internal resistor configurations. The series is designed for high-density surface-mount applications requiring reliable digital switching performance.
Replacement Considerations
Direct pin-compatible alternatives within the same family include DCX143EU-7-F and DCX143ZU-7-F. These parts share the same package and general electrical characteristics but utilize different internal resistor values. Verify resistor tolerances and ratios to ensure compatibility with existing circuit designs.
