DTA114ECA-TP

Overview

The DTA114ECA-TP is a single PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a pre-biased resistor network within an SOT-23 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance (R1) of 10 kΩ and a resistance ratio (R2/R1) of 1.0. It operates with a transition frequency of 250 MHz and supports a power dissipation of 200 mW at 25°C. The component is designed for inverter circuit configurations without external input resistors.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without connecting external input resistors
• Thin-film resistors provide complete isolation to allow negative biasing of the input
• Eliminates parasitic effects associated with discrete resistor networks
• Simplifies device design by requiring only on/off conditions to be set for operation

Applications

• Inverter circuits
• Logic level shifting
• Switching applications

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer. Counterfeit parts are a known industry risk; unauthorized sources do not receive warranty coverage. Confirm RoHS compliance status via official documentation, as the 'P' suffix indicates compliance. Ensure ordering quantities align with the standard 3Kpcs/Reel packing format specified by the manufacturer.

Selection Notes

Select this component for designs requiring a single PNP digital transistor with integrated biasing in an SOT-23 package. Verify that the -50 V supply voltage and -100 mA current ratings meet circuit requirements. Consider the 10 kΩ input resistance for base drive calculations. Ensure thermal management accommodates the 200 mW power dissipation limit and 625°C/W thermal resistance characteristics under expected ambient temperatures.
