DDC144TU-7

Overview

The DDC144TU-7 is a dual NPN digital transistor array manufactured by Diodes Incorporated, housed in an SOT363 surface-mount package. It integrates two discrete NPN transistors with built-in 47kΩ base resistors for logic switching applications. The device supports a maximum continuous collector current of 100mA and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a collector-emitter breakdown voltage (BVCEO) of 50V, a transition frequency (fT) of 250MHz, and a total power dissipation rating of 200mW at 25°C ambient temperature.

Feature Summary

• Integrates two discrete NPN transistors with built-in 47kΩ base resistors for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Compliant with RoHS standards and free from halogen and antimony

Applications

• Logic-switching applications controlled by microcontrollers
• Interface circuits utilizing comparators
• Standalone discrete device implementations

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the tape and reel packaging configuration containing 3000 units per carrier. Confirm that the component meets the required environmental compliance standards, specifically RoHS 3 and REACH regulations, as indicated in the manufacturer's documentation. Ensure the selected variant matches the intended application requirements regarding lead-free and green material specifications.

Selection Notes

Select this component when a dual NPN configuration with integrated base biasing is required for space-constrained designs. The SOT363 package offers a compact footprint suitable for high-density PCB layouts. Consider the 47kΩ internal resistor value to ensure compatibility with the driving logic levels and desired switching speeds. Verify thermal management needs against the 200mW power dissipation limit and derating curves provided in the datasheet.
