Procurement Notes

Verify the specific suffix 'PNE' against official Infineon documentation to confirm binning or tape-and-reel specifications. Confirm end-of-life status prior to design-in, as availability may be restricted. Ensure compliance with RoHS directives relevant to the target market. Cross-reference datasheet revisions to validate parameter consistency during procurement.

Selection Notes

Select this component when a compact NPN transistor with 45V breakdown is required. Compare hFE gain bands if specific amplification levels are critical. Verify thermal management requirements against the 330 mW dissipation limit. Consider pinout compatibility with existing SOT-323 footprints during schematic capture.

Part Context

This part belongs to the BC847 series of NPN transistors. It shares the same electrical ratings as other variants in the family but differs in packaging or binning codes. The BC847 series is widely used in low-power analog and digital switching applications. Variants typically share the SOT-23 or SOT-323 form factors.

Replacement Considerations

Direct substitutes include BC847B, BC847C, and BC847D in SOT-323 packages. Verify that alternative parts meet the 45V VCEO and 100mA IC requirements. Check for identical pin configurations to ensure mechanical interchangeability without PCB redesign.
