Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix when purchasing. The datasheet indicates that adding the suffix 'TIN/LEAD' requests Tin/Lead plated devices, while 'PBFREE' requests Lead-Free plating. Ensure the procurement order explicitly matches the required plating specification to align with the component's physical attributes and regulatory compliance needs.

Single Bipolar Transistors Selection Notes

Select this component for designs prioritizing high DC current gain and low noise figures in a small form factor. The SOT-323 package suits space-constrained layouts. Verify thermal management requirements against the 455 °C/W thermal resistance rating and ensure operating conditions remain within the specified voltage and current limits for optimal performance.

Single Bipolar Transistors Part Context

This part belongs to the CMST5086/CMST5087 series of PNP silicon transistors. Both variants share identical electrical ratings and package dimensions, differing primarily in marking codes. The CMST5087 is marked with '2QC'. The series is engineered for surface mount technology applications demanding superior gain and minimal noise interference.

Single Bipolar Transistors Replacement Considerations

The CMST5086 serves as a direct functional substitute within the same series, sharing identical electrical specifications and the SOT-323 package. Selection should focus on verifying pinout compatibility and ensuring the replacement meets the specific plating requirements of the target application.
