Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package marking matches FM20 (TO-220F) specifications. Ensure storage temperature remains within -55°C to +150°C prior to assembly. Check datasheet revision status as this component is noted as not recommended for new designs.

Single Bipolar Transistors Selection Notes

Select this component for high-current switching tasks requiring substantial base drive capability. The high hFE allows efficient control with lower input currents. Consider thermal management requirements given the 30W power dissipation limit. Evaluate compatibility with complementary PNP devices if push-pull configurations are required.
