Overview
The 84CNQ040S2 is a Schottky diode module manufactured by SMC Diode Solutions, designed for high-current rectification applications. It features a common cathode configuration with two independent channels housed in a PRM2-SL surface-mount package. The device supports an average rectified current of 40A per channel and withstands a maximum DC reverse voltage of 40V. Key electrical characteristics include a forward voltage of approximately 620mV at 80A total load and a low reverse leakage current of 1mA at the rated voltage. Operating junction temperature ranges from -55°C to 175°C.
Feature Summary
- Dual-channel Schottky barrier rectifier structure
- High thermal efficiency via PRM-SL surface mount packaging
- Low forward voltage drop for improved system efficiency
Applications
- DC-DC converter modules
- Power supply freewheeling circuits
- Industrial power distribution systems
Procurement Notes
Verify the specific suffix 'S2' against the manufacturer's latest datasheet to confirm pinout compatibility and mechanical dimensions. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the PRM2-SL package variant matches the intended PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when dual-channel rectification is required in a compact surface-mount form factor. The 40A per channel rating suits moderate-to-high current loads. Evaluate thermal management needs due to the 175°C junction limit. Compare forward voltage specifications against alternative packages to ensure optimal efficiency for the target application design.
Part Context
This part belongs to the 84CNQ series of Schottky diode arrays from SMC Diode Solutions. It utilizes the PRM2-SL package, which is optimized for surface-mount technology. The series is engineered for robust performance in power electronics, offering reliability under high-temperature conditions typical in industrial and automotive environments.
Replacement Considerations
Direct substitutes may include other 40V 40A dual Schottky modules in similar packages. Verify equivalent current ratings and thermal resistance values. Cross-reference pin assignments to ensure functional compatibility without circuit redesign.
