Single Bipolar Transistors Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verify availability through authorized distributors only, noting that supply is limited to existing stock. Confirm exact replacement compatibility before procurement, as the part is no longer in active production. Ensure all ordering suffixes match the original specification requirements for your design.

Single Bipolar Transistors Selection Notes

Select this component only if legacy design compatibility is required, as it has been superseded by newer alternatives. Evaluate the FCX491TA or FCX491ATA for direct replacements depending on the specific gain bin previously utilized. Consider thermal management requirements carefully due to the 1 W power dissipation limit in the SOT89-3L package without adequate PCB heat sinking.

Single Bipolar Transistors Part Context

The 2DD1766R-13 belongs to the 2DD1766P/Q/R series of NPN surface mount transistors from Diodes Incorporated. This series was designed to offer complementary PNP types and support automated assembly. The R variant specifically denotes a particular DC current gain bin within the family, optimized for consistent performance in standard switching and amplification roles.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly identifies the FCX491TA and FCX491ATA as the recommended replacements for the obsolete 2DD1766R-13. Verify pinout and electrical parameter alignment before substitution.
