Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source when sourcing this component, as Fairchild Semiconductor's discrete product lines have undergone corporate transitions. Confirm that the received units match the original Fairchild specifications rather than subsequent rebranded versions if strict adherence to the original datasheet parameters is required for your design. Check for any obsolescence notices or lifecycle status updates from authorized distributors before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select the FJC790TF when a PNP transistor with a 40V voltage rating and 2A current capacity is needed in a small surface-mount form factor. Its high junction temperature rating makes it suitable for environments where thermal management is critical. Ensure the application does not exceed the 500mW power dissipation limit under worst-case operating conditions to maintain reliability and prevent thermal runaway during operation.

Single Bipolar Transistors Part Context

This component belongs to the FJC790 series of single bipolar transistors. The series was originally developed by Fairchild Semiconductor for specialized applications such as camera flash systems. While the broader semiconductor landscape has shifted due to industry mergers, this specific part number remains documented in historical technical literature and distributor archives for reference and legacy system maintenance purposes.

Single Bipolar Transistors Replacement Considerations
