Single FETs, MOSFETs Procurement Notes

Verify the specific suffix against official documentation, as variations may exist between F and L designations within the same voltage and current class. Confirm that the required package type matches the TO-264AA footprint and pinout. Ensure the supply chain source provides valid manufacturer traceability and RoHS compliance certificates. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement specifications.

Single FETs, MOSFETs Selection Notes

Select this component when a 500 V rating and 84 A current capacity are required in a through-hole configuration. Compare the 65 mΩ on-resistance against alternative packages to evaluate thermal management requirements. Consider the 340 nC gate charge for driver selection and switching loss calculations. Verify that the application environment supports the specified -55°C to +150°C operating temperature range without derating constraints.

Single FETs, MOSFETs Part Context

This part belongs to the APT series of fast recovery MOSFETs designed for high-efficiency power switching. It utilizes advanced silicon planar technology to balance low on-resistance with reliable switching performance. The TO-264 package provides superior heat dissipation compared to smaller surface-mount options, making it suitable for high-power industrial applications where thermal robustness is critical.

Single FETs, MOSFETs Replacement Considerations
