FET, MOSFET Arrays Procurement Notes

Verify the specific suffix -F085 against the official datasheet to confirm packaging and tape-and-reel specifications. Confirm AEC-Q101 automotive qualification status if required for your application. Check for end-of-life notices as Fairchild Semiconductor products may have transitioned statuses under onsemi. Ensure RoHS compliance documentation is available for regulatory adherence.

FET, MOSFET Arrays Selection Notes

Select this component when dual N-Channel logic-level MOSFETs are needed for low-voltage switching. Compare rDS(on) values at 4.5V and 10V VGS against system drive voltages. Consider the thermal performance and package type for heat dissipation needs. Verify that the dual-channel architecture fits the board space constraints compared to discrete single-channel alternatives.

FET, MOSFET Arrays Part Context

This part belongs to the PowerTrench family from onsemi (formerly Fairchild Semiconductor). It represents a continuation of legacy Fairchild designs now managed by onsemi. The FDS8949 series is known for its balance of low RDS(on) and fast switching speeds, making it suitable for modern power management ICs and motor drivers.

FET, MOSFET Arrays Replacement Considerations

Check for direct pin-compatible replacements within the onsemi portfolio such as other FDS89xx variants. Verify equivalent rDS(on) and gate charge specifications. Ensure any substitute maintains AEC-Q101 qualification if used in automotive contexts. Consult distributor cross-reference tools for updated availability.
