DTA014EUBTL

Overview

The DTA014EUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within a compact SOT-323FL-3 (UMT3F) surface-mount package. It operates with a maximum collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an internal resistor ratio of 1:1, with typical input resistance values of 10kΩ. Key electrical specifications include a minimum DC current gain (hFE) of 35 at -5mA and -10V, a transition frequency of 250MHz, and a power dissipation rating of 200mW.

Feature Summary

• Integrates dual biasing resistors to simplify circuit design by eliminating the need for external input components.
• Provides high-speed switching capabilities suitable for applications requiring fast response times.
• Utilizes a low-profile surface-mount package optimized for space-constrained printed circuit board layouts.

Applications

• Inverter circuits in portable electronic devices
• Driver circuits for logic interfaces
• Switching applications in consumer electronics

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Ensure compliance with RoHS directives and confirm the specific tape-and-reel packaging quantity matches project requirements. Cross-reference datasheet revisions to guarantee parameter consistency during procurement.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for signal inversion or switching. Consider the 10kΩ internal resistance value for base drive compatibility. Evaluate the -50V voltage rating against system supply levels to ensure adequate safety margins under operational conditions.

Part Context

This part belongs to the DTA series of pre-biased transistors from ROHM Semiconductor. These devices combine a single bipolar junction transistor with two internal resistors to form a complete digital switching unit. The UMT3F package variant offers a small footprint compared to traditional discrete transistor arrangements.

Replacement Considerations

DTA114EUBHZG is listed as a similar specification replacement with identical electrical parameters but utilizes the UMT3 package instead of UMT3F. Verify pinout compatibility and physical dimensions before substituting.
