DTA123EMFHAT2L

Overview

DTA123EMFHAT2L is a PNP digital transistor with built-in resistors, manufactured by ROHM Semiconductor. It features an SOT-723 (VMT3) surface-mount package. Key electrical parameters include a collector-emitter voltage of -50 V, a continuous collector current of -0.1 A, and a power dissipation of 0.15 W. The device incorporates input resistance R1 of 1 kΩ to 2.2 kΩ and emitter-base resistance R2 of 1 kΩ to 2.2 kΩ. It meets the AEC-Q101 automotive grade standard. The component is marked as Not Recommended for New Designs.

Feature Summary

• Integrates biasing resistors directly with the PNP transistor to simplify circuit design.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components.

Procurement Notes

This component is designated as Not Recommended for New Designs. Procurement should be limited to supporting existing production lines. Verify that the specific suffix matches the required packaging and tolerance specifications before ordering, as availability may be restricted to legacy stock or specific distributor channels.

Selection Notes

Select this part only for retrofitting or maintaining existing designs where the SOT-723 form factor and specific resistor ratios are mandatory. For new projects, consider alternative ROHM digital transistors that are currently recommended for new designs to ensure long-term supply stability and updated manufacturing support.

Part Context

The DTA123 series represents ROHM's standard line of digital transistors. This specific variant utilizes the compact VMT3 package, suitable for space-constrained applications. While it shares core characteristics with other DTA123 models, the EMFHA suffix denotes specific internal configurations and packaging details unique to this designation within the broader product family.
