Single Bipolar Transistors Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing updates may occur. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation. Ensure the TO-92 package variant matches your PCB footprint requirements. Check for any recent Product Change Notifications that might affect pinout or material composition before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring moderate current handling up to 100 mA with reliable switching characteristics. The high current gain simplifies base drive circuitry compared to lower-gain alternatives. Consider the 625 mW power dissipation limit when designing thermal management solutions. The TO-92 package is appropriate for through-hole assembly processes rather than surface-mount requirements.
