Procurement Notes

Verify the complete part number including suffixes such as TF1G against official onsemi documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested component matches the specific CoolMOS L2 generation, as minor suffix variations may indicate different testing conditions or packaging formats. Always cross-reference the manufacturer's latest datasheet for any updates to electrical limits or recommended operating areas prior to final procurement.

Selection Notes

Select this component when designing circuits requiring a balance between low conduction losses and fast switching speeds at 600V ratings. Ensure the thermal management solution can handle the power dissipation associated with the specified Rds(on) at the expected operating current. Verify that the gate drive voltage aligns with the threshold requirements for full enhancement without exceeding maximum gate-source voltage limits during transient events.

Part Context

This device belongs to onsemi's CoolMOS L2 family, which represents an evolution in superjunction MOSFET technology. The L2 series specifically targets improvements in figure-of-merit by reducing both on-resistance and gate charge compared to previous generations. It serves as a direct upgrade path for designs previously using standard 600V MOSFETs where efficiency and size reduction are critical priorities.

Replacement Considerations

Direct replacements must match the 600V/20A specification and TO-247-3 package. Verify pinout compatibility and thermal resistance values. Substitutes should offer comparable or lower Rds(on) and gate charge to maintain circuit efficiency. Check for equivalent avalanche rating if the application demands high ruggedness.
