DTA014TMT2L

Overview

The DTA014TMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within a compact SOT-723 (VMT3) surface-mount package. This single-element device integrates an NPN driver transistor and resistors to simplify circuit design. Key electrical specifications include a collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 150 mW. The typical input resistance is 10 kOhms with a resistor ratio of 1, ensuring straightforward interface capabilities for low-power switching applications.

Feature Summary

• Integrates NPN driver transistor and bias resistors to eliminate external components
• Simplifies circuit design by requiring only on/off condition settings
• Compact SOT-723 package suitable for space-constrained surface-mount applications

Applications

• Interface circuits between logic gates and loads
• Driver stages for relays and small motors
• Switching applications in portable electronic devices

Procurement Notes

Verify the specific suffix 'TMT2L' against the official ROHM datasheet to confirm the exact tape-and-reel packaging quantity and marking code. Ensure the procurement channel provides genuine components with traceable origin documentation to prevent counterfeit parts in critical designs.

Selection Notes

Select this component when a PNP digital transistor with 10 kOhm input resistance and -50 V breakdown voltage is required. Compare the 150 mW power dissipation limit against thermal constraints. Verify that the SOT-723 footprint matches the PCB layout requirements and that the hFE characteristics meet the switching speed needs.

Part Context

This part belongs to the ROHM DTA series of digital transistors, which are designed to replace discrete resistor-transistor networks. The DTA014 variant specifically denotes a PNP type with equal internal resistors (R1=R2). It serves as a standard solution for replacing multiple discrete components with a single integrated device.

Replacement Considerations

Check for direct substitutes such as DTC014TMT2L (NPN complement) or other ROHM DTA014 variants with different packages like DTA014EMT2L. Verify pinout compatibility and electrical parameter equivalence before substitution.
