Procurement Notes

Verify the specific manufacturer source when sourcing this component, as historical data indicates production by Sanyo Semiconductor prior to corporate restructuring. Confirm that the part number corresponds to the original Sanyo specifications rather than generic onsemi equivalents. Ensure the MCPH package variant matches the required footprint dimensions for PCB integration.

Selection Notes

Select this component for applications requiring low-voltage operation with a maximum collector-emitter voltage of 3.5 V. The 2 GHz transition frequency makes it suitable for UHF and lower X Band frequencies. Consider the 120 mW power dissipation limit when designing thermal management solutions for continuous operation.

Part Context

This component belongs to the family of small-signal RF transistors optimized for high-frequency analog circuits. The MCPH package provides a standardized footprint for automated assembly. Historical records associate this specific part number with Sanyo Semiconductor's product line before its acquisition by onsemi.

Replacement Considerations

Public documentation lists the BFP640FESDH6327XTSA1 (Infineon) and MMBTH10-TP (Micro Commercial Components) as similar replacement options. Verify pinout compatibility and RF parameters against the original design requirements before substitution.
