DTA143XUA-TP

Overview

The DTA143XUA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single bipolar junction transistor with an internal base resistor within a compact SOT-323 surface-mount package. The device features a typical input resistance of 4.7 kOhms and a standard resistor ratio of 10. Key electrical specifications include a maximum operating frequency of 250 MHz, a minimum DC collector-to-base gain (hFE) of 80, and a power dissipation rating of 200 mW. The component supports operation at temperatures up to +150°C and is designed for high-speed switching applications requiring minimal external biasing components.

Feature Summary

• Integrates a PNP transistor with a built-in 4.7 kOhm base resistor to simplify circuit design.
• Optimized for high-frequency performance with a transition frequency of 250 MHz.
• Utilizes the SOT-323 package to enable efficient space-saving surface-mount assembly.

Applications

• High-speed switching circuits in consumer electronics
• Driver stages for logic interfaces and level shifting
• Biasing networks in RF signal processing modules

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout compatibility and electrical tolerances. Ensure that the sourcing channel provides valid manufacturer traceability. Confirm RoHS compliance status through current datasheets before integration into regulated assemblies.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The 4.7 kOhm internal resistor value suits standard logic interface applications. Verify that the 200 mW power dissipation limit aligns with the thermal management capabilities of the target PCB layout.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from Micro Commercial Components. The series offers various resistor values and configurations to accommodate different drive requirements. The XUA suffix typically denotes specific packaging or variant characteristics within the broader DTA143 family line.

Replacement Considerations

Cross-reference with other manufacturers' PNP digital transistors featuring similar 4.7 kOhm base resistors and SOT-323 footprints. Verify that substitute parts match the 250 MHz frequency rating and 200 mW power dissipation limits to ensure functional equivalence.
