Single FETs, MOSFETs Procurement Notes

Verify component status before procurement as the RCX450N20 is designated as Not Recommended for New Designs (NRND). This designation indicates that while production may continue to support existing customers, the manufacturer does not recommend incorporating this part into new product developments. Confirm availability and lead times directly with authorized distributors or the manufacturer to ensure supply continuity for ongoing projects.

Single FETs, MOSFETs Selection Notes

Select this component when a robust N-channel MOSFET with high current capacity is required in a through-hole package. The 10V drive characteristic allows compatibility with standard logic-level drivers without complex level shifting. Consider the thermal management requirements associated with the TO-220FM-3 package and the 40W power dissipation limit under your specific operating conditions.

Single FETs, MOSFETs Part Context

This part belongs to the RCX series of 10V drive N-channel power MOSFETs from ROHM Semiconductor. The series focuses on reducing driver complexity while maintaining high performance. The RCX450N20 specifically targets applications needing 200V blocking capability and significant current handling in a traditional leaded package format.

Single FETs, MOSFETs Replacement Considerations

The RCJ450N20TL is a surface-mount equivalent within the same family offering identical electrical characteristics in a TO-263S package. Designers transitioning from through-hole to surface-mount should verify footprint compatibility and thermal dissipation differences between the TO-220FM and TO-263S packages.
