DTA124EUA-TP

Overview

The DTA124EUA-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 to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 200 mW at 25°C. The device features a typical input resistance (R1) of 22 kΩ with a resistance ratio (R2/R1) of 1.0. It exhibits a transition frequency of 250 MHz and a minimum DC current gain of 56. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Built-in thin-film bias resistors enable inverter configuration without external input components.
• Complete isolation of internal resistors allows for negative biasing of the input terminal.
• Elimination of parasitic effects through integrated resistor architecture simplifies device operation.

Applications

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

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 prior to integration. Ensure storage conditions adhere to Moisture Sensitivity Level 1 requirements to maintain device integrity during assembly processes.

Selection Notes

Select this component for designs requiring a PNP digital transistor with integrated biasing in a compact SOT-323 footprint. Verify that the -50 V collector-emitter voltage and -100 mA current ratings align with the specific load requirements. Consider the 22 kΩ input resistance value for base drive calculations. Ensure thermal management supports the 200 mW power dissipation limit within the intended ambient temperature range.

Part Context

This part belongs to the DTA124 series of pre-biased transistors produced by Micro Commercial Components. The 'EUA' suffix denotes the specific PNP variant housed in the SOT-323 package. The '-TP' suffix indicates tape and reel packaging containing 3000 pieces per reel. This series is designed to replace discrete resistor-transistor combinations in space-constrained digital applications.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-323 package having similar -50 V ratings and ~22 kΩ input resistance. Verify pinout compatibility and electrical characteristics such as hFE and saturation voltage before substitution.
