Single FETs, MOSFETs Procurement Notes

Verify the specific package variant, as the L2 series includes TO-247, TO-268, and TO-264 options. Confirm that the application requires linear mode capability rather than standard switching. Ensure thermal management aligns with the 150°C junction limit. Check for updated datasheets from Littelfuse or authorized distributors to confirm current manufacturing status and pinout compatibility.

Single FETs, MOSFETs Selection Notes

Select this component when linear operation stability is critical, distinguishing it from standard switching MOSFETs. The 500V rating suits medium-voltage industrial applications. Consider the TO-247 package for through-hole mounting and high thermal dissipation needs. Evaluate the 0.17Ω Rds(on) against system efficiency requirements under linear bias conditions.

Single FETs, MOSFETs Part Context

This part belongs to the Littelfuse L2 Series of N-Channel Linear MOSFETs. The series covers voltage ratings from 75V to 600V. The IXTH40N50L2 represents the 500V, 40A segment. It shares design principles with other L2 devices but offers specific electrical parameters tailored for higher voltage linear applications.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include other L2 series devices like IXTH40N30L2 if voltage requirements allow. Cross-brand equivalents must be verified for linear FBSOA guarantees. Standard switching MOSFETs are not suitable replacements due to lack of linear operation certification.
