Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to confirm the lead configuration before integration. The absence of a suffix indicates a side collector arrangement, while the 'C' suffix designates a center collector layout. Ensure the selected variant matches the intended PCB footprint and pin assignment requirements for the target application.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate power handling and defined hFE ranges is required. Consider the thermal resistance of 310 °C/W for heat dissipation planning. Evaluate the specific hFE classification letter needed for the circuit's gain requirements to ensure proper performance margins.

Single Bipolar Transistors Part Context

This part belongs to the KSC series of NPN transistors originally developed by Fairchild Semiconductor. Following corporate integration, these components are now managed under the ON Semiconductor portfolio. The datasheet reflects the historical Fairchild designation while noting the transition to the current manufacturer branding.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly identifies the KSA539 as the direct complement to this device. Verify pin compatibility and electrical ratings against other general-purpose NPN transistors if considering alternative sources.

Single Bipolar Transistors FAQ

How does the ordering suffix affect the physical pinout?

The presence or absence of a suffix determines the lead arrangement. A non-suffix part uses a side collector configuration (Emitter, Base, Collector), whereas the 'C' suffix indicates a center collector configuration (Emitter, Collector, Base).

What is the maximum collector current rating?

The absolute maximum rating for the collector current (IC) is specified as 200 mA.

Is this device suitable for automotive applications?

No. The authorized use policy states that this product is not intended for automotive or transportation applications unless specifically approved in writing by a company officer.
