Procurement Notes
This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Engineers must confirm the specific obsolescence date and lead time constraints before initiating procurement processes to ensure supply continuity.
Selection Notes
Designers should evaluate alternative components within the same Vishay series that offer similar electrical specifications and pin compatibility. Verify that replacement parts maintain the required thermal resistance and package dimensions to fit existing footprints without redesigning the printed circuit board layout.
Part Context
This part belongs to the Vishay Siliconix TrenchFET family, designed for efficient power switching in compact form factors. The TSSOP-8 package provides a balance between thermal dissipation capabilities and space efficiency for modern electronic assemblies.
Replacement Considerations
Consult official datasheets for cross-reference recommendations from Vishay. Ensure any substitute device matches the -20V rating, -7.9A current capacity, and 10mΩ on-resistance requirements.
