Overview
The 81CNQ045 is a Schottky diode module manufactured by SMC Diode Solutions. It features a common cathode configuration with two diodes housed in the PRM2 package. The device supports a maximum repetitive peak reverse voltage of 45 V and an average rectified forward current of 80 A per diode. The typical forward voltage drop is 740 mV at 80 A, with a maximum reverse leakage current of 5 mA at 45 V. Operating junction temperature ranges from -55°C to 175°C.
Feature Summary
- Schottky barrier technology for low forward voltage drop and high efficiency
- Common cathode dual-diode configuration within a single chassis-mount module
- High thermal stability suitable for demanding power applications
Applications
- DC-DC converter circuits
- Free-wheeling rectification in motor drives
- Power supply output rectification
Procurement Notes
Verify the specific suffix against the official datasheet to confirm exact electrical tolerances and pinout compatibility. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Confirm that the PRM2 package dimensions match the target chassis mounting requirements before finalizing orders.
Selection Notes
Select this component when a 45 V rating and 80 A current capacity are required in a compact chassis-mount form factor. Compare the 740 mV forward voltage drop against system efficiency targets. Verify that the thermal management solution can handle the heat dissipation associated with the specified current levels in the PRM2 package.
Part Context
This part belongs to the 81CNQ series of Schottky rectifier modules designed for high-current applications. The series utilizes advanced silicon carbide or specialized silicon processes to achieve fast switching characteristics. The PRM2 package provides robust mechanical stability for industrial environments.
Replacement Considerations
Direct replacements must match the 45 V reverse voltage, 80 A current rating, and PRM2 package footprint. Verify that alternative Schottky modules maintain similar forward voltage characteristics to ensure circuit performance parity.
