Procurement Notes
This component is officially listed as End-of-Life (EOL) and is no longer manufactured by onsemi. Availability is restricted to existing stock from third-party distributors. Verification of part authenticity and storage history is critical due to the discontinued status. Buyers should confirm current supplier inventory levels and lead times directly with authorized channels before procurement.
Selection Notes
Engineers selecting this part must account for its discontinued status. Alternative solutions should be evaluated based on pin compatibility and thermal performance. Since new production is unavailable, design-in decisions should prioritize components with active manufacturing support to ensure long-term supply chain stability for mass production.
Part Context
The STK621 series represents onsemi's legacy line of three-phase inverter hybrid ICs. These modules combine power MOSFETs or IGBTs with driver logic in a compact form factor. The STK621-024A-E specifically targets applications requiring integrated phase control without external discrete gate drivers, simplifying board layout and reducing component count in motor drive designs.
Replacement Considerations
As the STK621-024A-E is end-of-life, direct substitutes are not explicitly confirmed in public documentation. Designers should consult onsemi for recommended cross-reference parts or evaluate compatible three-phase inverter hybrids from other manufacturers that meet the original electrical specifications.
