DTA124EEBTL

Overview

The DTA124EEBTL is a pre-biased PNP digital transistor manufactured by Rohm Semiconductor. It integrates bias resistors (R1 and R2) within a single EMT3 surface-mount package to simplify circuit design. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (Ic) of -30 mA, and a maximum power dissipation (Pd) of 150 mW. The device features an input resistance (R1) of 22 kOhms and an emitter-base resistance (R2) of 22 kOhms. It operates with a DC current gain (hFE) of at least 56 at -5 mA and -5 V, and supports a transition frequency of 250 MHz.

Feature Summary

• Integrates built-in bias resistors to eliminate the need for external input components in inverter circuits.
• Provides simplified on/off control logic through a single-component solution.

Applications

• Inverter circuits requiring simplified input stages
• General-purpose switching applications
• Interface driver circuits

Procurement Notes

Verify the specific suffix 'TL' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and quantity. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the EMT3 package dimensions with the PCB footprint library to guarantee mechanical compatibility during placement.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required for space-constrained designs. The 22 kOhm resistor values are suitable for standard logic interface levels. Consider the 150 mW power dissipation limit and -50 V voltage rating to ensure operation within safe thermal and electrical boundaries for the intended load conditions.

Part Context

This part belongs to the DTA124 series of pre-biased transistors from Rohm Semiconductor. It serves as the PNP counterpart to the DTC124E series NPN devices. The EMT3 package offers a small form factor compared to larger SOT packages, making it appropriate for high-density surface mount assemblies where board space is limited.

Replacement Considerations

Direct replacements include the DTA124EEB or DTA124XE3HZGTL, provided the package type and electrical ratings match the design requirements. Verify that substitute parts maintain the same resistor ratios and hFE characteristics to ensure circuit stability.
