DTC144EMFHAT2L

Overview

The DTC144EMFHAT2L is a PNP digital transistor with built-in resistors, manufactured by ROHM Semiconductor. It features a VMT3 (SOT-723) surface-mount package with three terminals. Key electrical parameters include a collector current of -0.1 A, power dissipation of 0.15 W, and an input resistance (R1) of 47 kΩ. The device supports an AEC-Q101 automotive grade standard, with a supply voltage of 1 V to 50 V and a minimum hFE of 68. Operating temperatures range from -55°C to 150°C storage.

Feature Summary

• Integrates bias resistors for simplified circuit design
• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact SOT-723 surface-mount packaging

Applications

• Automotive electronic circuits requiring robust component reliability
• General-purpose digital switching applications
• Interface circuits for logic level translation

Procurement Notes

Verify the specific suffix 'T2L' against official ROHM documentation to confirm tape-and-reel specifications and exact marking codes. Confirm that the AEC-Q101 qualification status applies to this specific variant. Check for any obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required in a compact form factor. Ensure the 47 kΩ input resistance matches the driving source impedance requirements. Verify that the 0.15 W power dissipation rating is sufficient for the intended thermal environment and duty cycle.

Part Context

This part belongs to the DTC144 series of digital transistors, which combine NPN or PNP transistors with internal bias resistors. The EMFHAT2L designation indicates a specific package type (VMT3/SOT-723) and polarity (PNP). This series is designed to reduce board space and simplify assembly by eliminating external resistor components.

Replacement Considerations

Direct substitutes must match the PNP polarity, SOT-723 package, and 47 kΩ resistor values. Verify equivalent AEC-Q101 compliance if automotive use is required. Cross-reference with other ROHM variants in the DTC144 family for pin-compatible alternatives.
