• Switched-mode power supplies

Procurement Notes

Verify the specific suffix 'S3' against official datasheets to confirm the exact electrical characteristics and pinout configuration, as suffixes often denote specific testing or packaging variations. Ensure compatibility with existing PCB footprints and thermal management solutions before integration.

Selection Notes

Select this component for applications requiring robust high-voltage switching with efficient thermal handling. Compare the 40A current rating and 1200V breakdown voltage against system requirements. Consider the TO-247 package size for mechanical constraints and heat dissipation needs relative to alternative packages.

Part Context

This part belongs to onsemi's NGTB series of IGBTs designed for industrial and consumer applications. The series leverages trench gate technology to improve switching speed and reduce power loss compared to older planar designs, targeting efficiency improvements in power conversion systems.

Replacement Considerations

Check for direct replacements like the NGTB40N120FL3WG or NGTB40N120L3WG from onsemi, which share similar voltage and current ratings but may differ in specific switching parameters or thermal resistance values.
