Procurement Notes

Verify the specific ordering suffix to confirm packaging type. The TR-E suffix indicates tape and reel delivery, whereas the non-trailing variant typically uses tube packaging. Confirm RoHS compliance status and Ecopack2 designation during procurement to ensure adherence to environmental standards required for the target assembly process.

Selection Notes

Select this component when designing circuits requiring high gain and broad bandwidth in the VHF/UHF range. Ensure the PCB layout accommodates the exposed bottom pad of the PowerSO-10RF package for effective heat dissipation. Verify that the gate drive circuitry supports the 20 V maximum gate-source voltage limit under all operating conditions.

Part Context

This part belongs to the RFXL series of RF power LDMOS transistors from STMicroelectronics. It utilizes the PowerSO-10RF package, which was developed to provide superior thermal performance and power density compared to traditional bipolar technologies. The series targets applications needing reliable surface-mount solutions for RF power generation.

Replacement Considerations

The PD57018-E serves as the tube-packaged equivalent of this component. Both variants share identical electrical characteristics and functionality. Selection between them depends solely on manufacturing automation requirements rather than performance differences.
