Procurement Notes

Verify the component against the official Sanken datasheet specifications before integration. Confirm that the TO-220F package dimensions match your PCB footprint requirements. Ensure thermal management solutions align with the 35W dissipation rating at 25°C case temperature. Check for any specific ordering suffixes that may indicate packaging variations or testing standards.

Selection Notes

Select this transistor when designing circuits requiring high current switching with moderate voltage ratings. The TO-220F package facilitates direct mounting to heat sinks for effective thermal management. Consider the hFE minimum of 150 for base drive calculations. Evaluate the thermal resistance characteristics if operating near the maximum junction temperature limit of 150°C.
