FET, MOSFET Arrays Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entity ON Semiconductor, noting that acquisition history may affect branding on final components. Confirm the package type matches the required D2PAK footprint and pin configuration. Ensure RoHS compliance status aligns with project requirements. Cross-reference the specific suffix TM with official documentation to confirm tape-and-reel packaging specifications if applicable.

FET, MOSFET Arrays Selection Notes

Select this component when a 500V N-Channel MOSFET with moderate current handling is required. The 0.65 ohm RDS(on) makes it suitable for applications where conduction losses must be minimized without requiring ultra-low resistance devices. Consider the thermal characteristics of the D2PAK package for heat dissipation needs. Compare against similar FDP series parts for potential form-fit-function alternatives if supply constraints exist.

FET, MOSFET Arrays Part Context

This part belongs to the Fairchild N-Channel MOSFET family, specifically the 500V rating class. It shares technological similarities with the FDP12N50 and FDI12N50, utilizing the same planar stripe DMOS process. These devices are commonly used in industrial and consumer electronics where reliability and switching efficiency are critical. The D2PAK package provides a balance between thermal performance and surface-mount convenience.

FET, MOSFET Arrays Replacement Considerations

Potential substitutes include the FDP12N50 and FDI12N50 from the same manufacturer family. Verify pinout compatibility and thermal resistance values before substitution. Check for equivalent RDS(on) and gate charge specifications to ensure circuit performance remains within design limits.
