FET, MOSFET Arrays Procurement Notes

Verify the specific suffix 'PBF' confirms lead-free compliance and RoHS standards as per Infineon's current product status documentation. Confirm the package type matches the required PCB footprint for SO-8. Check for any recent lifecycle notices regarding obsolescence or recommended replacements before finalizing procurement plans.

FET, MOSFET Arrays Selection Notes

Select this component when a dual N-channel topology is required in a small outline package. Ensure the application voltage remains below the 20 V limit and that the thermal design can handle the specified power dissipation. Verify that the gate drive voltage meets the minimum threshold for optimal RDS(on) performance.

FET, MOSFET Arrays Part Context
