Single Bipolar Transistors Procurement Notes

This component is officially discontinued and scheduled for obsolescence by the manufacturer. Sourcing new original units may be difficult as production has ceased. Buyers should verify the authenticity of available stock carefully. Consider evaluating alternative replacement parts that meet the same electrical requirements to ensure long-term project viability and supply chain stability.

Single Bipolar Transistors Selection Notes

Select this part only if legacy compatibility is required or if specific historical design constraints mandate its use. Verify that the 450V rating and 2A current capacity align precisely with the target circuit's maximum operating conditions. Ensure the TO-220 package fits the existing thermal and mechanical layout. Due to discontinuation, confirm availability through authorized distributors before finalizing the design.

Single Bipolar Transistors Part Context

The KSC5402 series belongs to Fairchild's lineup of high-voltage NPN transistors. The DTTU suffix indicates a specific tape-and-reel packaging variant within the TO-220 form factor. This family was engineered for robust performance in demanding power electronics environments, providing a balance of voltage handling and switching speed for industrial and consumer applications.
