Procurement Notes

Verify current availability status as the part may be discontinued or have limited supply. Confirm RoHS compliance details via official documentation. Check for Product Change Notifications regarding metallization switches from AlSiCu to AlCu on LDMOS technologies. Ensure handling procedures account for moisture sensitivity classification.

Selection Notes

Select this component for designs requiring 45 W output power at 945 MHz with 13 dB gain. Ensure the circuit supports 28 V operation in common source mode. Verify compatibility with the PowerSO-10RF package for surface mount assembly. Consider thermal management requirements due to high power dissipation characteristics.

Part Context

This part belongs to the PD57045-E series within STMicroelectronics' LdmoST plastic family. It is distinct from the SD57045 variants which use different packaging. The TR-E suffix indicates reel packaging. It serves as a lateral MOSFET solution for RF power amplification in the 1 GHz range.

Replacement Considerations

Check for direct substitutes within the PD57045 series. Evaluate SD57045 variants if package differences are acceptable. Review PCN documents for any material changes affecting electrical parameters before substitution.
