FET, MOSFET Arrays Procurement Notes

Verify component authenticity through authorized distribution channels only. Confirm the specific ordering suffix matches the required tape and reel quantity. Check for recent product change notices or end-of-life declarations prior to finalizing procurement plans to ensure supply continuity.

FET, MOSFET Arrays Selection Notes

Select this component when a dual N-channel MOSFET with low Rds(on) and high current capability is required in a small footprint. Ensure the application voltage remains below the 40V Vdss limit. Verify that the thermal design can handle the specified power dissipation and that the gate drive voltage supports the 10V test conditions for optimal resistance performance.

FET, MOSFET Arrays Part Context

This part belongs to onsemi's PowerTrench family, known for low on-resistance and fast switching speeds. The FDMD8240L utilizes the Power Clip package to minimize thermal resistance, making it suitable for high-power density applications compared to standard DFN packages.

FET, MOSFET Arrays Replacement Considerations

Check for direct pin-compatible alternatives within the same PowerTrench series. Verify that any substitute maintains the 40V rating and comparable Rds(on) values. Ensure the replacement package matches the PQFN-12 dimensions for board compatibility.
