84CNQ045S2

Overview

The 84CNQ045S2 is a Schottky diode rectifier array manufactured by SMC Diode Solutions. It features a common cathode configuration with two diodes, rated for a maximum DC reverse voltage of 45 V and an average rectified current of 40 A per diode. The component utilizes the PRM2-SL surface-mount package and operates within a junction temperature range of -55°C to 125°C. It exhibits a forward voltage drop of approximately 740 mV at full load and maintains low reverse leakage characteristics suitable for high-efficiency power conversion applications.

Feature Summary

• Schottky technology ensures low forward voltage drop for improved energy efficiency
• Common cathode dual-diode configuration simplifies circuit design
• Surface-mount PRM2-SL package facilitates automated PCB assembly
• High-temperature epoxy encapsulation provides mechanical strength

Applications

• DC-DC converter modules
• Low-voltage high-current power supplies
• Point-of-load (POL) regulation circuits
• Freewheeling diodes in synchronous rectification topologies

Procurement Notes

Verify the specific suffix 'S2' against official manufacturer documentation to confirm exact pinout and thermal specifications, as variations may exist within the series. Ensure compatibility with RoHS3 compliance requirements if mandated by your project standards. Cross-reference the PRM2-SL package dimensions with your PCB footprint library to guarantee accurate placement and soldering reliability during manufacturing.

Selection Notes

Select this component when designing systems requiring efficient rectification at low voltages near 45 V. The 40 A rating per diode supports substantial current loads in compact surface-mount form factors. Consider the 125°C junction temperature limit for thermal management strategies. This device is appropriate for applications prioritizing speed and low conduction losses over high-voltage blocking capabilities.

Part Context

This part belongs to the 84CNQ series of Schottky rectifier arrays from SMC Diode Solutions. The series offers various voltage ratings and current capacities in standardized packages like PRM2-SL. These modules are engineered for robust performance in industrial and consumer electronics where space constraints and thermal efficiency are critical design parameters.

Replacement Considerations

Direct substitutes include the 84CNQ045SL from SMC Diode Solutions, which shares identical electrical ratings and the PRM2-SL package.
