Low on-state resistance for efficient conduction
Robust unclamped inductive surge energy tolerance

Applications

Switching regulators
Power amplifiers
DC-DC converters

Procurement Notes

Verify the component datasheet directly from Sanken Electric to confirm electrical parameters and physical dimensions. Ensure the TO-220S package matches your PCB footprint requirements. Check that the specific lot meets your thermal management needs given the junction-to-ambient resistance values provided in the official documentation.

Selection Notes

Select this component when a 40V N-channel MOSFET with high current capacity is required. Consider the low RDS(ON) for minimizing conduction losses in high-current paths. Evaluate the thermal resistance specifications against your heatsinking strategy to ensure safe operating temperatures under continuous load conditions.

Part Context

This MOSFET belongs to Sanken's discrete semiconductor lineup designed for general-purpose power switching. The TO-220S package provides a balance between thermal dissipation and mounting flexibility. It serves as a fundamental building block for various power electronics circuits requiring reliable voltage and current control.

Replacement Considerations

Consult official Sanken Electric documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' devices without verifying pinout, voltage ratings, and thermal characteristics against the original datasheet.
