Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'QX' against the official Nexperia datasheet to confirm it denotes the standard commercial or automotive grade variant without additional functional changes. Ensure the ordering part number matches the required packaging format, as suffixes often indicate reel specifications rather than electrical differences. Cross-reference the manufacturer's latest product change notices to confirm the active status and any recent label or assembly site updates.

Single Bipolar Transistors Selection Notes

Select this component when a compact footprint is required alongside high current handling capabilities. The exposed pad design necessitates careful PCB thermal management planning to maximize heat dissipation. Verify that the 45 V breakdown voltage aligns with the circuit's operating conditions. Consider the 180 MHz transition frequency for switching speed requirements relative to other available voltage variants within the series.

Single Bipolar Transistors Part Context

This device belongs to the BC5xPAS series of NPN medium-power transistors from Nexperia. The series offers multiple voltage ratings, including 45 V, 60 V, and 80 V versions, all sharing the same DFN2020D-3 package form factor. This specific model represents the 45 V variant within the lineup designed for space-constrained applications requiring robust performance.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BC54-10PASX and BC54PAS-QX from Nexperia. These alternatives share identical electrical specifications and package dimensions, allowing for direct pin-compatible replacement in existing designs.
