DDTA113ZUA-TP

Overview

The DDTA113ZUA-TP is a single PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates internal resistors R1 and R2 within an SOT-323 surface-mount package. The device supports a maximum supply voltage of -50 V and a continuous collector current of -50 mA. Electrical characteristics include a minimum DC current gain (hFE) of 80 at -50 mA and -5 V, with a typical input resistance of 1 kOhms and a resistor ratio of 10. Power dissipation is rated at 200 mW, and the component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates base and emitter resistors for simplified circuit design
• Halogen-free 'Green' device compliant with RoHS standards
• Moisture sensitivity level 1 rating for reliable handling

Applications

• General-purpose switching applications
• Driver circuits for relays and solenoids
• Logic level translation interfaces

Procurement Notes

Verify authenticity through authorized MCC distributors or direct channels. Counterfeit prevention requires checking packaging integrity and traceability documentation. Ensure ordering suffixes match specific compliance requirements such as halogen-free status. Confirm datasheet revisions align with manufacturing batches before procurement integration.

Selection Notes

Select this component for designs requiring a pre-biased PNP transistor in compact SOT-323 form factors. Verify that the -50V supply voltage and -50mA current limits accommodate the target load conditions. Consider the 1kOhm input resistance for appropriate base drive calculations. Ensure thermal management supports the 200mW power dissipation rating under expected operating temperatures.

Part Context

This part belongs to the DDTA113 series of pre-biased transistors from Micro Commercial Components. It serves as a discrete solution replacing multiple discrete components, reducing board space and assembly complexity. The ZUA suffix indicates the specific SOT-323 package configuration used for surface mount technology implementations.

Replacement Considerations

Direct substitutes include Diodes Incorporated DDTA113ZUA-7-F and Rohm Semiconductor DTA113ZUAT106. These alternatives share similar pinouts and electrical characteristics but may differ in specific parameter tolerances or packaging details. Verify compatibility with existing PCB footprints and circuit requirements before substitution.
