84CNQ035SM

Overview

The 84CNQ035SM is a Schottky diode array manufactured by SMC Diode Solutions, designed for high-efficiency power conversion applications. It features a dual common cathode configuration within a single package, providing two independent rectifying paths. The device is rated for a maximum repetitive peak reverse voltage of 35 V and supports an average rectified forward current of 80 A per diode. Utilizing PRM2-SM surface mount packaging, it ensures robust thermal performance and reliable operation in demanding electronic environments.

Feature Summary

• Dual common cathode configuration for efficient power management
• Schottky technology enabling low forward voltage drop and minimal switching losses
• Surface mount PRM2-SM package optimized for automated assembly and compact designs

Applications

• DC-DC converter modules requiring high current density
• Power factor correction circuits in industrial power supplies
• Free-wheeling rectification in synchronous buck converters

Procurement Notes

Verify the specific suffix SM against official datasheets to confirm the exact package variant and pinout compatibility with your PCB footprint. Ensure that the 35 V reverse voltage rating aligns with your circuit's peak inverse voltage requirements. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when designing systems that require high current handling capabilities in a surface mount form factor. The 80 A per diode rating makes it suitable for low-voltage, high-current output stages. Consider the thermal resistance characteristics of the PRM2-SM package during heat sink or copper plane design to maintain junction temperature within safe operating limits.

Part Context

This part belongs to the CNQ series of high-power Schottky rectifiers from SMC Diode Solutions. The series is engineered for applications demanding high reliability and efficiency in power electronics. The 84CNQ035SM specifically addresses the need for compact, high-current solutions in modern power supply architectures where space constraints are critical.

Replacement Considerations

Consult official cross-reference guides for equivalent parts with matching current and voltage ratings. Verify that any substitute maintains the same common cathode configuration and surface mount package dimensions to ensure mechanical and electrical compatibility without redesigning the board.
