- Free-wheeling diodes in inductive loads
- Power supply output rectification
Procurement Notes
Verify the specific suffix SM against the official datasheet to confirm the through-hole mounting style and lead configuration. Ensure the procurement documentation references the correct RoHS compliance status and environmental classifications provided by SMC Diode Solutions. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing orders.
Selection Notes
Select this component when a low-voltage, high-current rectification solution is required in a through-hole format. The 40 A rating and 40 V breakdown voltage define its operational limits. Consider the thermal management requirements associated with the PRM2-SM package and the specified junction temperature range to ensure reliable performance in the target application environment.
Part Context
This part belongs to the CNQ series of Schottky diode arrays from SMC Diode Solutions. These devices are engineered for robust performance in power conversion systems. The series offers various voltage and current ratings, with the 84CNQ040SM specifically addressing needs for moderate voltage and high current density in standard PCB layouts.
Replacement Considerations
Direct substitutes must match the 40V/40A rating, common cathode configuration, and PRM2-SM package dimensions. Verify that alternative parts maintain equivalent forward voltage characteristics and thermal resistance values to ensure circuit compatibility without redesign.
