Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations exist within the product family. Confirm that the component status aligns with project requirements, noting that certain variants may be designated as not recommended for new designs. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing specifications and quality standards.

Single Bipolar Transistors Selection Notes

Select this component when an NPN equivalent is required for complementary circuit designs, specifically the 2SCR544 series. Ensure the application voltage does not exceed the -80 V collector-emitter limit. Verify that the thermal design accommodates the 500 mW power dissipation in the MPT3 package. Consider the AEC-Q101 certification if the target application involves automotive systems requiring strict reliability standards.

Single Bipolar Transistors Part Context

This part belongs to the 2SxR series of middle-power transistors from ROHM Semiconductor. The series includes both NPN and PNP variants designed for automotive and industrial applications. These components are characterized by their high current handling capabilities and robust construction, making them suitable for driving loads in demanding electronic environments where long-term stability is critical.

Single Bipolar Transistors Replacement Considerations

The 2SAR544PHZGT100 is documented as a direct replacement with the same pinout and package. Both parts share identical electrical characteristics and are available in the MPT3 package. Verify availability status, as the PFRAT variant may have different production lifecycle statuses compared to the PHZG variant.
