Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix '-TP' indicates tape and reel packaging containing 3000 pieces per reel. Confirm that the 'C' designation corresponds to the hFE classification range of 270 to 560. Ensure compliance requirements match the lead-free and halogen-free specifications if applicable. Validate authenticity through authorized MCC distributors to avoid counterfeit components.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required in a SOT-323 package. The 'C' rank provides a minimum hFE of 270, suitable for low-current amplification. Consider the complementary 2SC1576A for push-pull configurations. Verify thermal management capabilities given the 200 mW power dissipation limit in small outline packages.

Single Bipolar Transistors Part Context

This part belongs to the 2SC4081 series of NPN silicon epitaxial transistors. It is designed as a general-purpose device compatible with surface mount assembly standards. The series includes variants distinguished by hFE ranking suffixes such as A, B, and C. The -TP suffix denotes the specific tape and reel packaging format used for automated placement.

Single Bipolar Transistors Replacement Considerations

The 2SC1576A serves as the complementary PNP counterpart within the same family. Other manufacturers produce equivalent NPN transistors in the SOT-323 package with similar 50V ratings and 150mA current limits. Verify pinout compatibility and electrical parameters before substitution.
