80CNQ040SL

Overview

The 80CNQ040SL is a Schottky diode array manufactured by SMC Diode Solutions. It features a dual common cathode configuration housed in the PRM2-SL surface mount package. The device supports a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 40 A per diode. It operates within a junction temperature range of -55°C to 150°C, with a specified maximum forward voltage drop at full load.

Feature Summary

• Schottky barrier technology for low forward voltage drop
• Dual common cathode configuration for efficient power conversion
• High purity epoxy encapsulation for mechanical strength

Applications

• DC-DC converters
• Free-wheeling diodes in switching circuits
• Power factor correction (PFC) circuits

Procurement Notes

Verify the specific suffix SL against the manufacturer's datasheet to confirm the exact pinout and tape-and-reel specifications. Ensure the component matches the required thermal management capabilities for the intended application environment. Cross-reference the RoHS compliance status with project requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-current, low-voltage surface mount solution is required. The PRM2-SL package offers a compact footprint suitable for dense PCB layouts. Evaluate the thermal resistance characteristics to ensure adequate heat dissipation under continuous 40 A operation conditions.

Part Context

This part belongs to the 80CNQ series of high-power Schottky rectifiers from SMC Diode Solutions. It shares design similarities with the 88CNQ060 but differs in voltage rating and packaging variant. The series targets industrial and automotive power supply applications requiring robust performance.

Replacement Considerations

Direct substitutes include the 88CNQ060, provided the higher voltage rating is acceptable. Verify pin compatibility and thermal characteristics before swapping components in existing designs.
