Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation on the datasheet to confirm Shenzhen Slkormicro Semicon Co., Ltd. origin, as the 2SC4081 part number is widely used by multiple vendors including ROHM and Nexperia. Ensure the specific suffix '-R' matches your supply chain requirements. Cross-reference electrical parameters such as hFE and Vceo against the official Slkormicro specification sheet before integration.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with 50V breakdown and 150mA current capacity is required in a SOT-323 package. It is appropriate for designs prioritizing space efficiency over high-power handling. Compare its 200mW thermal limit against your circuit's power dissipation needs to ensure reliable operation within the specified temperature range.

Single Bipolar Transistors Part Context

This component belongs to the family of general-purpose small-signal bipolar junction transistors (BJTs). Similar devices include the ROHM 2SC4081U3 and Nexperia 2PC4081Q.
