DTA023JUBTL

Overview

The DTA023JUBTL is a PNP pre-biased digital transistor manufactured by Rohm Semiconductor, designed for surface-mount applications in the UMT3F package. It integrates internal bias resistors to simplify circuit design. Key electrical specifications include a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 50 V. The device features a transition frequency of 250 MHz and a maximum power dissipation of 200 mW. Internal resistor values are specified as R1 = 2.2 kΩ and R2 = 47 kΩ. The component is AEC-Q101 qualified for automotive grade reliability.

Feature Summary

• Integrated bias resistors eliminate the need for external input components, reducing board space and assembly complexity.
• Automotive-grade qualification ensures high reliability and stability under demanding operating conditions.
• Compact UMT3F surface-mount package facilitates automated placement and efficient PCB layout.

Applications

• Interface circuits requiring signal level shifting or buffering.
• Driver stages for relays, solenoids, or small motors.
• Logic level translation between different voltage domains in embedded systems.

Procurement Notes

Verify the specific suffix 'UBTL' against the manufacturer's latest datasheet to confirm packaging type and reel specifications. Ensure compatibility with RoHS3 standards if required by the target application. Confirm that the automotive grade designation meets the specific environmental requirements of the end product before finalizing procurement.

Selection Notes

Select this component when a PNP configuration with a 2.2k/47k resistor ratio is required. Compare the 250 MHz transition frequency against higher-speed alternatives if switching performance is critical. Verify that the 100 mA collector current rating exceeds the maximum load current in the intended circuit to ensure safe operation margins.

Part Context

This part belongs to Rohm's DTA023 series of pre-biased transistors. It serves as a direct replacement for discrete BJT and resistor combinations, offering a standardized solution for digital switching applications. The UMT3F package variant provides a compact footprint suitable for modern high-density electronic designs.

Replacement Considerations

DTA023JU3HL is a similar specification alternative within the same family. Verify pinout compatibility and exact resistor tolerances before substitution. Check if the alternative package size fits the existing PCB land pattern without modification.
