Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'E' against the official datasheet to confirm packaging or compliance variations. Confirm RoHS status and REACH SVHC declarations directly from the manufacturer's documentation before integration. Ensure the source document explicitly lists the 2SC3950E part number to avoid confusion with standard variants.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high-speed switching or amplification in video signal paths. The 120 V rating and 500 mA current capacity define its operational limits. Consider the TO-126 package for through-hole mounting requirements. Verify thermal management needs based on the 1.3 W power dissipation rating under expected load conditions.
