Overview
The 81CNQ045SM is a Schottky diode module manufactured by SMC Diode Solutions. It features a common cathode configuration with one pair of diodes. The device supports a maximum DC reverse voltage (Vr) of 45 V and an average rectified current (Io) of 80 A per diode. The forward voltage (Vf) is specified at 740 mV when tested at 80 A. Reverse leakage current is limited to 5 mA at the rated 45 V. The component operates within a junction temperature range of -55°C to 175°C and utilizes the PRM2 package for chassis mounting.
Feature Summary
- Schottky technology provides fast recovery characteristics suitable for high-frequency applications.
- Common cathode dual-diode arrangement simplifies circuit design for bridge or center-tapped configurations.
- Chassis mount construction facilitates efficient thermal management in high-power environments.
Applications
- High-current DC power supply rectification
- Free-wheeling diodes in motor drive circuits
- Solar panel protection against reverse current
Procurement Notes
Verify the exact suffix designation during procurement, as the provided model includes 'SM' which may indicate specific packaging or terminal variations compared to standard 'S2' variants. Confirm RoHS3 compliance status and REACH registration details with the supplier prior to ordering. Ensure the chassis mounting interface matches the PRM2 footprint specifications required by the heat sink assembly.
Selection Notes
Select this component for applications requiring robust 80A handling capability with low forward voltage drop. The 45V rating suits low-voltage, high-current systems. Consider the PRM2 package constraints regarding thermal resistance and mechanical mounting torque. Compare leakage current specifications against system tolerance levels at maximum operating temperatures to ensure reliability.
Part Context
This part belongs to the 81CNQ series of Schottky diode modules from SMC Diode Solutions. The series offers various voltage and current ratings within the PRM2 form factor. These modules are designed for industrial power conversion needs, emphasizing durability and thermal performance in compact chassis-mounted designs.
Replacement Considerations
The 81CNQ045S2 is a verified alternative within the same series offering identical electrical parameters and PRM2 packaging. Verify pinout compatibility and thermal interface requirements before substitution.
