Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix matches the required hFE rank, as the 'S' designation specifies a gain range of 270 to 560. Confirm RoHS compliance status based on the specific suffix configuration. Ensure procurement channels are authorized distributors to guarantee component authenticity and traceability. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing design integration.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required to complement a 2SA1774 PNP device. The S-rank provides higher current gain than Q or R variants, suitable for sensitive amplification stages. Verify that the 150 mA collector current limit meets the load requirements. Consider the SOT-523 package constraints regarding thermal dissipation and solder pad layout during the PCB design phase.

Single Bipolar Transistors Part Context

This part belongs to the 2SC4617 family produced by Micro Commercial Components. The family includes Q, R, and S variants distinguished primarily by their DC current gain ranges. These transistors are designed for general-purpose amplification tasks requiring small form factors. The S variant specifically targets applications needing higher gain performance compared to the standard industry offerings.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other manufacturers' 2SC4617 parts such as those from ROHM or onsemi. Verify pinout compatibility with the SOT-523/EMT3 package. Ensure replacement devices meet the same voltage and current ratings. Cross-reference hFE bins if gain matching with a complementary PNP transistor is critical for the application.
