186NQ200-1

Overview

The 186NQ200-1 is a Schottky rectifier manufactured by SMC Diode Solutions, rated for 200 V DC reverse voltage and 180 A average forward current. It utilizes the PRM1-1 (Half Pak) module package designed for chassis mounting. The device features low forward voltage characteristics typical of Schottky technology, minimizing conduction losses in high-current applications.

Feature Summary

• Schottky barrier construction for low forward voltage drop
• High current capacity of 180 A per unit
• Chassis mount configuration for efficient thermal management

Applications

• High-power DC power supplies
• Industrial motor drives
• Solar PV string inverters

Procurement Notes

Verify the specific suffix and packaging variant against the manufacturer's latest datasheet before ordering. Confirm chassis mounting hole patterns and thermal interface requirements match the system design. Ensure compliance with RoHS3 standards if required by the end application specifications.

Selection Notes

Select this component for applications requiring high current handling with minimal switching losses. The Half Pak module form factor allows for direct heatsink attachment, simplifying thermal design compared to discrete components. Verify that the 200 V rating provides sufficient margin for the circuit's peak inverse voltage conditions.

Part Context

This part belongs to the 186NQ series of high-current Schottky rectifiers from SMC Diode Solutions. The series is engineered for robust performance in demanding power electronics environments, offering a balance of high current density and reliable operation under thermal stress.

Replacement Considerations

Direct substitutes include other 180 A, 200 V Schottky modules in the PRM1-1 package. Verify pinout compatibility and thermal resistance values when considering alternatives from different manufacturers.
