Procurement Notes
This component is officially listed as obsolete and no longer manufactured by onsemi. Availability is restricted to surplus or secondary market channels. Verify authenticity and storage history carefully when sourcing from non-original distributors. Ensure compatibility with existing designs before procurement due to end-of-life status.
Selection Notes
Select this part only if legacy design compatibility is required. As an obsolete component, it lacks current manufacturing support. Evaluate alternative modern three-phase inverter HICs from onsemi or other manufacturers for new designs to ensure long-term supply chain stability and updated feature sets.
Part Context
The STK621 series represents onsemi's line of hybrid integrated circuits for motor control. The STK621-728S-E variant integrates gate drivers and power switches for three-phase operation. It belongs to the broader category of power management ICs used in industrial and automotive sectors for efficient motor drive solutions.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements must be identified through independent engineering analysis of equivalent three-phase inverter HICs.
