Procurement Notes

Verify component status carefully as this part number is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets if immediate procurement is required. Ensure that any replacement strategy accounts for potential supply chain constraints associated with discontinued semiconductor components.

Selection Notes

Select this component specifically for designs requiring high-frequency performance with low noise characteristics in an automotive context. Consider the low voltage ratings and thermal dissipation limits when designing the circuit. Verify compatibility with existing PCB footprints for the TSFP-4 package before finalizing the design.

Part Context

This transistor belongs to the BFP540 series of RF bipolar transistors produced by Infineon Technologies. The series is characterized by the use of Silicon Germanium Carbon (SiGe:C) technology, which provides superior high-frequency performance compared to standard silicon devices. The specific suffix indicates the tape-and-reel packaging configuration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require consulting official Infineon obsolescence notices or evaluating alternative RF transistor families with similar frequency and gain specifications.
