Procurement Notes
Verify the specific manufacturing location and assembly details when sourcing this component, as Alpha & Omega Semiconductor has issued notices regarding manufacturing location changes for multiple products including the AO4498L. Ensure that the received units match the required specifications and packaging format. Contact the manufacturer or authorized distributors directly for sample schedules and confirmation of current production status before finalizing procurement plans.
Selection Notes
Select the AO4498L for designs requiring a 30 V N-channel MOSFET with high current handling capabilities in an 8-SOIC footprint. Its low on-resistance makes it suitable for improving efficiency in power conversion stages. Consider the thermal constraints associated with its 3.1 W power dissipation rating when designing heat dissipation solutions for the target application environment.
Part Context
This component belongs to the family of single FETs produced by Alpha & Omega Semiconductor Inc., specifically categorized under N-channel MOSFETs. It is part of a series that includes related models such as the AO4496 and AO4490L, which share similar voltage ratings but may differ in current handling or package configurations. The AO4498L is distinct for its combination of 30 V rating and 18 A current capability in the SOIC-8 form factor.
Replacement Considerations
The AO4496 and AO4490L are listed as comparable parts within the same product line. Verify electrical parameters and pin compatibility before substitution.
