Procurement Notes
This product is no longer manufactured by onsemi. Availability is limited to existing stock held by distributors such as Rochester Electronics. Verify part authenticity and storage conditions carefully when sourcing from secondary suppliers, as direct manufacturer support is discontinued.
Selection Notes
Select this component only if legacy compatibility with single-phase hybrid PFC topologies is required. Evaluate alternative modern onsemi PFC controllers for new designs due to the end-of-life status. Ensure thermal management supports the 223 W dissipation rating in the target enclosure.
Part Context
The STK760 series represents onsemi's hybrid approach to power factor correction, combining control logic and power switching elements. This specific model targets single-phase applications, offering a consolidated solution compared to discrete component implementations. It belongs to the broader portfolio of intelligent power solutions aimed at improving energy efficiency in industrial and consumer electronics.
Replacement Considerations
No official substitute part numbers are documented in public sources. Users must identify equivalent third-party components or newer onsemi generations independently based on electrical specifications and pinout compatibility.
