Single Bipolar Transistors Procurement Notes

Verify the specific suffix E6433 against official Infineon documentation to confirm manufacturing origin and compliance status. Confirm availability as this component may be subject to lifecycle restrictions or discontinuation. Ensure the ordering part number matches the required voltage and gain binning specifications for your design.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 65V breakdown voltage is required in a compact SOT-23 package. Consider the 250 MHz transition frequency for high-speed switching applications. Verify that the 330 mW power dissipation limit aligns with the thermal management capabilities of the target PCB layout.

Single Bipolar Transistors Part Context

This part belongs to the BC846 series of NPN transistors, distinguished by its 65V collector-emitter voltage rating compared to the lower-voltage BC848 variants. The E6433 suffix typically denotes a specific tape-and-reel packaging format and manufacturing lot code defined by Infineon for mass production distribution.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other 65V NPN SOT-23 transistors only after verifying pinout compatibility and electrical parameter equivalence through official datasheets.
