DTC144TMFHAT2L

Overview

The DTC144TMFHAT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in a VMT3 surface-mount package. It operates with a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device includes two 47kΩ resistors configured for potential divider applications. Key electrical specifications include a minimum DC current gain (hFE) of 68 at 5mA and 5V, a transition frequency of 250MHz, and a power dissipation rating of 150mW. The component supports a maximum operating temperature of +150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce board space
• Provides high-speed switching capability suitable for digital signal processing
• Engineered for automotive reliability with AEC-Q101 certification

Applications

• Automotive electronic control units requiring qualified discrete components
• General-purpose digital switching and level shifting circuits
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix 'TMFHAT2L' against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check for lead-free status if required by your manufacturing process. Confirm availability through authorized distributors as supply chain conditions may vary.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is needed for high-frequency applications. The VMT3 package offers a small footprint compared to standard SOT-23 variants. Consider the 50V rating and 100mA current capacity to ensure adequate headroom for your specific load requirements.

Part Context

This part belongs to the DTC144 series of Bias Resistor Built-in Transistors (BRBTs). The series provides various configurations including potential divider types and resistor-alone types in multiple package formats such as SOT-23, SOT-323, and VMT3. The DTC144TMFHAT2L specifically utilizes the VMT3 package for dense PCB layouts.

Replacement Considerations

Direct replacements within the same family include DTA144TMFHAT2L (PNP version) or other DTC144 variants with identical pinouts but different packages like DTC144ECA. Verify that substitute parts match the 50V VCEO and 100mA Ic ratings.
