DTA144EEBTL

Overview

The DTA144EEBTL is a single PNP digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications in the EMT3F (SOT-416FL) package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of -50 V and a continuous collector current of -30 mA. The device features a typical input resistance (R1) of 47 kOhms and an emitter-base resistance (R2) of 47 kOhms. It offers a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, and the maximum operating temperature reaches +150°C.

Feature Summary

• Integrates built-in bias resistors to enable inverter circuit configuration without external components
• Utilizes thin-film resistors with complete isolation to minimize parasitic effects
• Supports negative biasing of the input terminal

Applications

• Inverter circuits
• Interface logic
• Driver applications

Procurement Notes

Verify the specific suffix BTL indicates the tape-and-reel packaging format when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the EMT3F package dimensions match the target PCB footprint requirements for proper assembly.

Selection Notes

Select this component for designs requiring a compact PNP digital solution with integrated biasing. The 47kΩ resistor ratio suits standard logic interface levels. Consider the 150mW power dissipation limit for thermal management. Verify that the -50V rating meets the system's voltage requirements.

Part Context

This part belongs to the DTA144 series of digital transistors from ROHM. It is the PNP counterpart to the NPN DTC144EEBTL. Both share similar electrical characteristics and package types but differ in polarity. The series is designed for general-purpose switching and logic inversion tasks in consumer and industrial electronics.

Replacement Considerations

The complementary NPN type DTC144EEBTL may serve as a reference for polarity-specific design changes. No direct cross-brand substitutes are confirmed in the provided data. Verify pinout compatibility if considering alternative manufacturers.
