DTA144EUA-TP

Overview

The DTA144EUA-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 with complete isolation to enable negative input biasing and minimize parasitic effects. Key electrical specifications include a maximum supply voltage of -50 V, a collector current of -100 mA, and a power dissipation of 200 mW. The device features a typical input resistance of 47 kΩ, a DC current gain of 68, and a transition frequency of 250 MHz.

Feature Summary

• Built-in bias resistors allow for inverter circuit configuration without external input components
• Thin-film resistors provide complete isolation to facilitate negative biasing of the input
• Halogen-free construction meets UL 94 V-0 flammability rating

Applications

• Inverter circuits requiring simplified design
• Switching applications utilizing on/off conditions
• General-purpose digital logic interfacing

Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unverified sources lack traceability and quality assurance. Confirm RoHS compliance status via official documentation before integration into regulated assemblies.

Selection Notes

Select this component for designs requiring PNP switching with integrated base drive. Ensure the operating voltage does not exceed -50 V and the collector current remains within -100 mA limits. Verify thermal management capabilities for the SOT-323 package under expected ambient temperature conditions.

Part Context

This part belongs to the DTA144 series of pre-biased transistors. It serves as a compact solution for replacing discrete resistor-transistor combinations in space-constrained printed circuit board layouts while maintaining standard digital switching performance characteristics.

Replacement Considerations

Consult official datasheets for cross-reference compatibility. Verify pinout alignment and electrical parameter equivalence before substituting with alternative manufacturers' equivalents.
