Single Bipolar Transistors Procurement Notes

Verify the specific suffix B5003 against official Infineon documentation to confirm tape-and-reel specifications and binning parameters. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 65 V breakdown and 100 mA current capability is required in a small SOT-23 package. Consider the 250 MHz transition frequency for moderate-speed switching or amplification tasks where low power consumption is essential.

Single Bipolar Transistors Part Context

This part belongs to the BC846 series of general-purpose NPN transistors. It shares core electrical characteristics with other variants in the family but may differ in packaging or binning based on the manufacturer's suffix codes. It serves as a fundamental discrete semiconductor component for analog and digital circuit designs.

Single Bipolar Transistors Replacement Considerations

Cross-reference with BC846B equivalents from other manufacturers such as Nexperia or onsemi. Verify pinout compatibility and ensure that alternative parts meet or exceed the 65 V VCEO and 100 mA Ic ratings for direct substitution.
