DTA144VUA-TP

Overview

The DTA144VUA-TP is a pre-biased digital transistor manufactured by Micro Commercial Components (MCC). It belongs to the DTA144 series and is housed in an SOT-523 surface-mount package. The component integrates a PNP transistor with internal biasing resistors, designed for switching applications. Official specifications list it under the Transistors sub-category. Standard factory packaging quantities are documented at 3000 units per reel.

Feature Summary

• Integrates a single PNP transistor with built-in biasing resistors to simplify circuit design.
• Utilizes an SOT-523 surface-mount package for compact board space utilization.
• Designed as a pre-biased digital transistor for efficient signal switching.

Applications

• General-purpose digital switching circuits
• Interface driving for logic level translation
• Embedded system control signals

Procurement Notes

Verify availability status directly with authorized distributors, as supply constraints have been reported. Confirm the specific suffix 'VUA' corresponds to the required SOT-523 package variant. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference the manufacturer part number with distributor codes to prevent ordering errors due to similar naming conventions within the DTA144 family.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required. The SOT-523 package suits high-density PCB layouts. Verify that the internal resistor values meet the specific drive requirements of the application. Compare against other DTA144 variants to ensure the correct pinout and package type match the design constraints.

Part Context

This part is part of the DTA144 series from MCC, which includes various pre-biased transistors in different packages such as SOT-23 and SOT-323. The VUA suffix typically denotes the SOT-523 package configuration. It serves as a drop-in replacement for discrete resistor-transistor networks, reducing component count and assembly time in digital logic interfaces.

Replacement Considerations

Check for direct substitutes like DTA144VE-TP or DTA144VCA-TP, ensuring package compatibility. Verify electrical parameters against original design requirements before substitution.
