Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer lot and date code upon receipt, as this component is listed as obsolete or discontinued by the primary distributor. Confirm physical package integrity and pinout alignment with standard TO-92-3 specifications before integration into production assemblies to ensure compatibility with existing footprints.

Single Bipolar Transistors Selection Notes

Select this component when a PNP small-signal transistor with moderate voltage ratings and low noise characteristics is required. Ensure the design accommodates the 100 mA current limit and 500 mW power dissipation constraints. Consider thermal management requirements given the small plastic package size and limited heat sinking capability inherent to the TO-92 form factor.

Single Bipolar Transistors Part Context

This part belongs to the BC307/BC308/BC309 series of general-purpose NPN/PNP transistors. The 'A' suffix typically denotes a specific binning of DC current gain (hFE) ranges, offering tighter performance tolerances compared to standard variants within the same family line.
