FET, MOSFET Arrays Procurement Notes

Verify the specific suffix F085 against the manufacturer's latest datasheet to confirm packaging details and availability status. Ensure the procurement channel provides original onsemi components with traceable documentation. Cross-reference the 8-PowerTDFN footprint requirements with your PCB layout specifications before ordering.

FET, MOSFET Arrays Selection Notes

Select this component when a dual-N-channel configuration is required in a small form factor. The 40V rating and 5.8mΩ resistance make it suitable for low-voltage, high-current applications. Evaluate the thermal constraints of the 8-PowerTDFN package to ensure adequate heat dissipation for the intended 75W maximum power rating.

FET, MOSFET Arrays Part Context

This part belongs to onsemi's PowerTrench MOSFET family, known for optimized gate charge and low on-resistance. The FDWS9420 variant specifically addresses space-constrained designs requiring dual channels. The F085 suffix typically denotes the tape-and-reel packaging format used for automated surface-mount assembly processes.

FET, MOSFET Arrays Replacement Considerations

Direct substitutes must match the 40V/20A specification, 5.8mΩ Rds(on), and 8-PowerTDFN package. Verify pinout compatibility and thermal characteristics. Consult onsemi's official replacement guide or distributor cross-reference tools for validated alternatives.
