- Motor control applications
Procurement Notes
Verify the specific datasheet revision and electrical characteristics against your design requirements. Confirm that the 8-ECH package dimensions match your PCB footprint. Check availability status as some distributors may list end-of-life or alternative sources. Ensure thermal management solutions align with the 9A current rating.
Selection Notes
Select this component for applications requiring low Rds(on) in a small form factor. Compare gate charge and input capacitance values against switching frequency requirements. Evaluate thermal performance under continuous load conditions. Consider pin compatibility if replacing existing designs.
Part Context
This part belongs to onsemi's discrete semiconductor portfolio, specifically within the single FET/MOSFET category. It is designed for general-purpose switching applications where efficiency and size are critical factors. The 8-ECH package provides a balance between current capacity and board space constraints.
Replacement Considerations
DigiKey lists Rochester Electronics as a supplier, indicating potential end-of-life status. Verify functional equivalence with other 35V, 9A N-channel MOSFETs in similar packages before substitution.
