- Built-in biasing resistors simplify circuit design
- Halogen-free 'Green' device compliant with environmental standards
- Moisture sensitivity level 1 for robust handling
Applications
- Inverter circuits
- Interface drivers
- Switching applications
Procurement Notes
Verify the authenticity of the DTC143ZUA-TP by purchasing only from authorized MCC distributors or directly from Micro Commercial Components Corp. Unauthorized sources may provide parts lacking full traceability or failing to meet MCC quality standards. Ensure the ordering suffix -TP corresponds to the Tape & Reel packing format containing 3000 pieces per reel as defined in the official documentation.
Selection Notes
Select the DTC143ZUA-TP when an NPN digital transistor with integrated biasing is required for space-constrained designs using the SOT-323 package. Confirm that the 50 V supply voltage and 100 mA collector current ratings align with the target application's electrical requirements. Verify compatibility with the 4.7 kΩ input resistance and the specific logic levels needed for the intended switching or inversion function.
Part Context
The DTC143ZUA-TP belongs to the DTC143ZUA series of NPN digital transistors produced by Micro Commercial Components. This series integrates pre-biased resistors to reduce external component count. The -TP suffix indicates the specific packaging configuration available in tape and reel format, facilitating automated assembly processes for high-volume manufacturing environments.
Replacement Considerations
Consult the manufacturer's datasheet for cross-reference information regarding equivalent components. Ensure any substitute part matches the SOT-323 package dimensions, NPN polarity, and critical electrical parameters such as the 50 V breakdown voltage and 4.7 kΩ input resistance.
