Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or official channels. Confirm datasheet revision and ordering suffixes match requirements. Check for moisture sensitivity handling instructions during storage and assembly. Ensure compliance with RoHS directives if applicable to the specific manufacturing batch.

Selection Notes

Select based on required operating frequency within the 1 GHz limit and desired output power levels. Consider the 28 V supply voltage constraint and thermal management needs given the junction-to-case thermal resistance. Evaluate impedance matching requirements using provided S-parameter data for the specific bias conditions.

Part Context

This component belongs to the LdmoST Plastic Family of RF power transistors from STMicroelectronics. It is specifically engineered for high gain and broadband performance in surface-mount configurations. The PowerSO-10RF package represents a JEDEC-approved high-power SMD solution optimized for RF needs.

Replacement Considerations

PD57002S serves as a direct alternative with straight leads instead of formed leads. Verify pinout compatibility and mechanical dimensions before substitution. Electrical characteristics remain consistent between the two variants.
