DTA144ECA-TP

Overview

The DTA144ECA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates bias resistors within an SOT-23 package to simplify circuit design. Key electrical parameters 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 and a transition frequency of 250 MHz. It operates with a junction temperature up to 150°C and supports storage temperatures from -55°C to 150°C.

Feature Summary

• Built-in thin-film bias resistors enable inverter configuration without external input components
• Complete isolation of bias resistors allows for negative biasing of the input
• Eliminates parasitic effects associated with discrete resistor networks

Applications

• Inverter circuits requiring simplified input configurations
• Switching applications utilizing on/off condition settings
• Digital logic interface circuits

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to ensure traceability and quality standards. Counterfeit parts pose significant risks; unauthorized sources do not receive warranty coverage. Confirm RoHS compliance via the 'P' suffix designation and check datasheet revisions for specific ordering information before procurement.

Selection Notes

Select this component for designs requiring a PNP digital transistor with integrated biasing in an SOT-23 package. Ensure the application voltage does not exceed -50 V and current limits remain within -100 mA. Consider the 47 kΩ input resistance and 250 MHz transition frequency for signal integrity requirements. Verify thermal management capabilities against the 200 mW power dissipation limit.

Part Context

The DTA144ECA belongs to the DTA series of pre-biased PNP transistors from Micro Commercial Components. This series combines NPN and PNP options in compact surface-mount packages to reduce board space and assembly complexity. The ECA variant specifically denotes the SOT-23 packaging format with defined resistance values.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-23 package having similar -50V ratings and ~47kΩ input resistance. Verify pinout compatibility (IN, GND, OUT) and electrical characteristics such as hFE and saturation voltage before substitution.
