DTA143ZUA-TP

Overview

The DTA143ZUA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-323 surface-mount package. It integrates thin-film bias resistors to simplify circuit design. Key electrical parameters include a maximum supply voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 200 mW at 25°C. The device features a typical input resistance (R1) of 4.7 kΩ with a resistance ratio (R2/R1) of 10. It exhibits a transition frequency of 250 MHz and a minimum DC current gain of 80. The component operates within a junction temperature range up to +150°C and is available in tape-and-reel packaging.

Feature Summary

• Built-in bias resistors enable inverter configuration without external input components
• Thin-film resistors provide complete isolation for negative biasing capability
• Halogen-free construction compliant with green product standards
• Moisture sensitivity level 1 classification for handling

Applications

• Inverter circuits requiring simplified input configurations

Procurement Notes

Verify the authenticity of the DTA143ZUA-TP through authorized MCC distributors or direct channels to ensure full traceability and compliance with quality standards. Confirm that the ordering suffix indicates RoHS compliance. Check datasheet revisions for any updates to mechanical dimensions or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs using the SOT-323 package. Ensure the application voltage does not exceed the -50 V limit and that the thermal environment supports the 200 mW power dissipation rating. Verify compatibility with the specified 4.7 kΩ input resistance for the target logic levels.

Part Context

This part belongs to the DTA143ZUA series of pre-biased PNP transistors from Micro Commercial Components. It is designed as a complementary counterpart to NPN variants within the same family, offering identical functional characteristics but with opposite polarity. The series focuses on reducing board space and component count by integrating internal bias networks.

Replacement Considerations

Compatible substitutes include other PNP digital transistors in the SOT-323 package with similar electrical ratings, such as the DTC143ZUA complement or equivalent parts from other manufacturers like ROHM or Taiwan Semiconductor, provided pinouts and electrical limits match.
