Procurement Notes

Verify the component status as obsolete or discontinued through official manufacturer channels before procurement planning. Confirm that the specific YTA suffix corresponds to the required packaging configuration. Ensure compatibility with existing circuit designs given the historical nature of this Fairchild Semiconductor part number now managed under the onsemi portfolio.

Selection Notes

Select the KSC2786YTA when designing circuits requiring high-frequency performance up to 100 MHz with low noise characteristics. Consider the 20 mA collector current limit and 250 mW power dissipation constraints during thermal management. Evaluate the hFE classification requirements (R, O, or Y) to match the necessary DC current gain range for the specific amplifier or oscillator application.

Part Context
