DTC114EMFHAT2L

Overview

The DTC114EMFHAT2L is an NPN digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications. It integrates a single transistor with built-in bias resistors within a VMT3 (SOT-723) package. The device supports a supply voltage up to 50V and handles a collector current of 0.1A. Key electrical parameters include an input resistance (R1) ranging from 1kΩ to 10kΩ and an emitter-base resistance (R2) between 1kΩ and 10kΩ. The DC current gain (hFE) is specified at 30 or higher. It operates within a storage temperature range of -55°C to 150°C and features a power dissipation capacity of 0.15W.

Feature Summary

• Integrates NPN transistor with built-in bias resistors to simplify circuit design
• Complies with AEC-Q101 automotive grade standards for reliability
• Utilizes compact VMT3 surface-mount packaging for space-efficient layouts

Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• General-purpose switching applications in consumer electronics
• Interface circuits for microcontrollers and logic gates

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Ensure compliance with RoHS directives if applicable to your manufacturing process. Check for obsolescence status as this part may be restricted to existing customer support rather than new designs.

Selection Notes

Select this component when an NPN digital transistor with integrated biasing is required in a compact SOT-723 form factor. Consider the specific resistor values (R1/R2 ratios) available within the series to match input impedance requirements. Verify that the 0.15W power dissipation rating suits the thermal environment of the target application.

Part Context

This part belongs to the DTC114 series of digital transistors from ROHM Semiconductor. The series offers various packages including SOT-23, SOT-323, and SOT-416 variants. The EMFH variant specifically denotes the VMT3 package and AEC-Q101 qualification, distinguishing it from standard commercial grade parts in the same family.

Replacement Considerations

Direct substitutes must match the NPN polarity, 50V VCEO, 100mA Ic, and VMT3/SOT-723 package. Verify equivalent hFE and resistor ratios. Other ROHM parts like DTC114WE or DTC114EETL share similar electrical characteristics but differ in package type.
