Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Check for RoHS compliance documentation and humidity sensitivity handling requirements during storage and assembly. Confirm package integrity as the unit utilizes a tray packaging format requiring specific handling protocols to prevent damage to the sensitive semiconductor junctions.

Selection Notes

Select this component for wideband applications requiring high power density up to 2 kW within the HF to 500 MHz spectrum. Ensure thermal management solutions accommodate the chassis-mounted D4E package design. Consider the large gate voltage range if designing for Class C amplifier configurations to optimize efficiency and linearity performance in demanding RF environments.

Part Context

This part belongs to the RF5L series of unmatched LDMOS FETs from STMicroelectronics. It shares architectural similarities with the RF5L051K0CB4 but offers higher power output. The series is characterized by high efficiency and linear gain, targeting wideband commercial and industrial sectors where robust performance under varying load conditions is critical.

Replacement Considerations

The RF5L052K0CB4 has been officially discontinued as of July 22, 2024. No direct functional substitutes are listed in official documentation. Designers should evaluate alternative high-power LDMOS transistors from other manufacturers or consider redesigning for lower power densities if compatible components are available.
