DTA014EEBTL

Overview

The DTA014EEBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an EMT3F (SOT-416FL) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -50 mA. The device includes a base resistor (R1) and an emitter-base resistor (R2), both typically rated at 10 kOhms, resulting in a resistance ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 35 at specific test conditions, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. The unit supports operation up to +150°C and complies with RoHS standards.

Feature Summary

• Integrates pre-biased resistors to simplify circuit design by eliminating external components.
• Provides high-speed switching capabilities suitable for signal processing applications.
• Utilizes a compact SMD package to minimize board space requirements.

Applications

• General-purpose logic level shifting and inversion circuits
• Driver stages for small-signal switching applications
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct packaging and specifications. Confirm that the intended application does not require automotive qualification, as this component is designated for standard-grade use only. Cross-reference datasheet revisions to validate electrical parameters prior to final procurement decisions.

Selection Notes

Select this component when a PNP digital transistor with 10 kOhm input resistance is required. Ensure the operating voltage remains within the -50 V limit and current stays below 50 mA. Consider the thermal constraints imposed by the 150 mW power dissipation rating in the EMT3F package during high-frequency switching operations.

Part Context

This component belongs to the DTA014 series of digital transistors from ROHM Semiconductor. It serves as a pre-biased solution designed to replace discrete resistor-transistor combinations. The EMT3F package offers a small footprint compared to larger transistor packages, facilitating dense PCB layouts for consumer electronics and industrial control systems.

Replacement Considerations

Direct substitutes may include other PNP digital transistors with similar 10 kOhm resistor ratios and -50V ratings, such as the DTA014EUBTL or DTC014EEBTL (NPN counterpart). Verify pinout compatibility and electrical limits before substitution.
