Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'B' against the manufacturer datasheet to confirm the exact hFE binning, as this indicates a specific gain range within the standard BC307 family. Ensure the procurement source provides documentation confirming the lead-free status and RoHS compliance for the specific batch. Cross-reference the pinout configuration in the official Fairchild datasheet to prevent installation errors during assembly.

Single Bipolar Transistors Selection Notes

Select the BC307B when a PNP transistor with low noise characteristics is required for small-signal tasks. The 45 V collector-emitter voltage and 100 mA current limits define its operational boundaries. Consider the TO-92 package constraints for thermal management and board space. Verify that the minimum hFE of 120 meets the circuit's gain requirements without external compensation.

Single Bipolar Transistors Part Context

The BC307 series represents a line of general-purpose PNP transistors widely used in analog electronics. The BC307B variant specifically denotes a unit selected for its guaranteed minimum current gain.
