Procurement Notes
This component carries an NRND status, indicating it is not recommended for new designs. Verification of current lifecycle status and potential obsolescence is critical before integration into any project. Availability may be limited as manufacturers typically phase out such components in favor of newer alternatives.
Selection Notes
Engineers should evaluate this part against active replacements due to its non-recommended-for-new-design status. Considerations must include verifying the specific frequency requirements against the HF to 250 MHz operational range. Thermal management and impedance matching networks should be designed to accommodate the 1.3 kW power handling capabilities effectively.
Part Context
The RF5L051K4CB4 belongs to STMicroelectronics' RF5L series of LDMOS transistors. This family focuses on high-power RF amplification for broadcast and industrial sectors. Similar models in the series often vary in power ratings or frequency bands while maintaining comparable packaging and technology nodes.
Replacement Considerations
Public documentation confirms the RF5L051K5CB4 as a related variant offering 1.5 kW power. Designers should consult official datasheets to verify pin compatibility and electrical parameter differences when considering substitution.
