Procurement Notes
Verify the exact ordering suffix against official documentation to confirm lead-free plating status. Confirm that the TO-92 through-hole package matches the target PCB layout requirements. Ensure the component meets specific environmental compliance standards required for the final assembly process before placing orders.
Selection Notes
Select this component when designing circuits requiring low noise characteristics combined with high-frequency response. The specified voltage ratings must align with the operating conditions of the target application. Consider the thermal dissipation capabilities within the TO-92 package for continuous operation limits.
Part Context
This part belongs to the Central Semiconductor small-signal transistor family, specifically categorized for RF oscillator use. It shares the standard TO-92 physical footprint with other discrete transistors in the series but differs significantly in its electrical profile, particularly regarding noise figure and transition frequency specifications.
Replacement Considerations
Direct substitutes such as the PN3564 or PN3565 share similar packaging but exhibit different voltage and gain characteristics. Verify pinout compatibility and ensure replacement devices meet the specific noise and frequency requirements of the original design.
