DTA113ZUA-TP

Overview

The DTA113ZUA-TP is a digital transistor manufactured by Micro Commercial Components (MCC). It features an NPN bipolar junction transistor with built-in biasing resistors. The device operates with a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Internal resistance values include a base resistor (R1) of 1kΩ and an emitter-base resistor (R2) of 10kΩ. Key electrical parameters specify a DC current gain (hFE) of at least 33, a transition frequency of 250MHz, and power dissipation of 200mW. It is housed in a SOT-323 surface-mount package.

Feature Summary

• Integrates NPN transistor with dual internal biasing resistors for simplified circuit design
• Optimized for high-speed switching applications with specified transition frequency
• Constructed using epitaxial planar die technology for reliability

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Biasing networks in amplifier configurations

Procurement Notes

Verify the complete part number including the -TP suffix to ensure RoHS compliance status matches project requirements. Confirm the specific manufacturing date code and lot traceability upon receipt. Cross-reference the datasheet revision against the component marking to ensure parameter consistency. Validate that the SOT-323 footprint aligns with the PCB layout specifications before final assembly.

Selection Notes

Select this component when an NPN configuration with 1kΩ input resistance is required. Ensure the 50V voltage rating and 100mA current capacity exceed the maximum load conditions. Verify that the SOT-323 package dimensions fit the available board space. Compare the 200mW power dissipation limit against the expected thermal environment to prevent overheating during operation.

Part Context

This component belongs to the DTC/DTA113 series of pre-biased transistors from MCC. It serves as a compact alternative to discrete resistor-transistor combinations. The device simplifies layout by integrating necessary biasing components into a single three-terminal package. It is designed for surface-mount assembly processes.

Replacement Considerations

DTC113ZUAT106 is listed as a recommended replacement with the same pinout and package. DTC113ZU3T106 is also identified as a compatible substitute maintaining identical physical and electrical characteristics.
