DTA024EEBTL

Overview

The DTA024EEBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device incorporates two internal resistors, R1 and R2, both valued at 22kΩ, eliminating the need for external components in inverter configurations. Key electrical parameters include a DC current gain (hFE) of 56 minimum and a power dissipation rating of 0.15W. The component is housed in an EMT3F package (SOT-416FL), measuring 1.6x1.6mm with a thickness of 0.85mm, suitable for surface mount applications.

Feature Summary

• Integrated biasing resistors enable direct connection to logic outputs without external input resistors.
• Compact SMD footprint facilitates high-density PCB layouts.
• Single PNP configuration simplifies switching and inverter circuit implementation.

Applications

• Logic level shifting between microcontrollers and peripheral devices
• Inverter circuits in embedded systems
• Switching applications for low-power signal processing

Procurement Notes

Verify the specific suffix 'TL' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact resistor values and polarity required for the target design to avoid functional mismatches.

Selection Notes

Select this component for designs requiring a pre-biased PNP switch with 22kΩ internal resistors. Compare against complementary NPN types like the DTC024E series if dual-polarity switching is needed. Verify that the 50V breakdown voltage and 100mA current limits exceed the maximum operational requirements of the application circuit.

Part Context

This part belongs to ROHM's standard digital transistor family, which integrates bipolar junction transistors with built-in bias resistors. These components are designed to reduce board space and assembly costs by replacing discrete resistor-transistor networks. The DTA024EEBTL specifically serves as a PNP variant within this standardized lineup.

Replacement Considerations

Check for direct substitutes such as the DTC024EEBTL for NPN equivalents or other PNP digital transistors with identical 22kΩ/22kΩ resistor ratios and compatible EMT3F/SOT-416FL packaging from the same manufacturer.
