Procurement Notes

Verify the specific suffix 'SR5' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as per current manufacturer declarations. Check for obsolescence notices or lifecycle status updates from NXP/Freescale. Ensure compatibility with NI-780S footprint designs during procurement planning.

Selection Notes

Select this component for S-band applications requiring high output power density. Compare gain and efficiency curves against alternative devices in the MRF6S series. Verify thermal resistance specifications match the intended heatsink design. Ensure biasing circuits support the required 28V operating voltage for optimal performance.

Part Context

This part belongs to the MRF6S family of LDMOS transistors, widely used in cellular base stations. The '24' designation typically refers to the S-band frequency coverage (2.3-2.5 GHz). The '140' indicates the nominal output power class. These devices represent a generation of RF power solutions transitioning from older TO-220 packages to advanced surface-mount technologies for higher integration densities.

Replacement Considerations

Direct replacements may include other MRF6S series variants with similar power ratings but different frequency bands, such as MRF6S21100HSR5 for lower frequencies. Cross-reference pinouts and thermal characteristics carefully. Consult manufacturer substitution guides for equivalent performance in S-band applications.
