Procurement Notes

Verify the specific ordering suffix STR-E against official STMicroelectronics documentation to confirm the tape and reel packaging format. Ensure compatibility with moisture sensitivity levels and handling requirements specified in the datasheet before procurement. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for designs requiring 3 W output power at 500 MHz with 17 dB gain. It is suitable for 12 V common source operation up to 1 GHz. Consider the PowerSO-10RF package for surface mount assembly. Verify thermal management capabilities align with the 31.7 W power dissipation rating and operating temperature range.

Part Context

This part belongs to the PD55003-E series of RF power transistors. It shares core specifications with the PD55003-E but differs in packaging. The standard PD55003-E uses a tube package, while the PD55003STR-E utilizes tape and reel packaging for automated assembly. Both are N-channel enhancement-mode lateral MOSFETs.

Replacement Considerations

PD55003-E is the equivalent part number with identical electrical characteristics but different packaging (Tube vs. Tape and Reel).
