Procurement Notes

Verify the specific suffix SMS2 against official datasheets to confirm pinout and thermal pad configurations, as variations exist within the CNQ series. Ensure the sourcing channel provides original manufacturer documentation to validate RoHS3 compliance and authenticity before integration into production designs.

Selection Notes

Select this component when designing systems requiring 45 V blocking capability with 80 A continuous current handling in a compact surface-mount form factor. Compare thermal resistance values against system heat dissipation requirements to ensure reliable operation within the specified 175°C junction temperature limit.

Part Context

This part belongs to the 84CNQ series of high-current Schottky rectifiers from SMC Diode Solutions. The series is engineered for demanding power conversion environments where low conduction losses and fast switching speeds are critical. The PRM2-SM package offers a balance between high current capacity and PCB space efficiency compared to through-hole alternatives.

Replacement Considerations

Cross-reference with other 80 A, 45 V Schottky arrays in the PRM2-SM package. Verify that substitute parts match the exact forward voltage and leakage specifications to maintain circuit performance and thermal management integrity.
