DTA124EKA-TP

Overview

The DTA124EKA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single bipolar junction transistor with built-in bias resistors in an SOT-23-3L surface-mount package. Key electrical specifications include a maximum collector current of -100 mA, a power dissipation rating of 200 mW, and a typical input resistance (R1) of 10 kOhms. The device features a typical resistor ratio of 1 and supports operation up to a maximum temperature of +150 C.

Feature Summary

• Integrates a PNP transistor with internal base and emitter bias resistors for simplified circuit design.
• Utilizes an SOT-23-3L surface-mount package suitable for automated assembly processes.
• Designed for high-temperature operation with a maximum junction temperature rating of +150 C.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for low-current loads requiring pre-biased control.
• Logic interface circuits between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific suffix 'EKA' against the manufacturer's official datasheet to confirm the exact pinout and resistor values, as variations exist within the DTA124 series. Ensure compliance with RoHS requirements by checking the latest product change notifications or certification documents provided by MCC prior to final procurement decisions.

Selection Notes

Select this component when a PNP digital transistor with a 10 kOhm base resistor is required in an SOT-23-3L footprint. Compare the 200 mW power dissipation limit against thermal constraints. Verify that the -100 mA collector current meets load requirements. Consider alternative packages like SOT-523 if space is more critical than thermal performance.

Part Context

This part belongs to the DTA124EKA series of pre-biased transistors from Micro Commercial Components. It is categorized under discrete semiconductor products, specifically single NPN/PNP digital transistors. The component is designed to replace multiple discrete components, reducing board space and assembly complexity in modern electronic designs.

Replacement Considerations

Cross-reference with other manufacturers offering PNP digital transistors in SOT-23-3L packages with similar 10 kOhm base resistance. Verify pin compatibility and electrical ratings such as Vceo and hFE before substitution.
