180NQ045R-1

Overview

The 180NQ045R-1 is a Schottky rectifier manufactured by SMC Diode Solutions, designed for high-power applications. It features a maximum repetitive peak reverse voltage of 45 V and an average forward current rating of 180 A. The component utilizes a PRM1-1 Half Pak module package, enabling chassis mounting. It supports junction temperatures up to 150°C. This device replaces three parallel DO-5 diodes, offering a lower profile and easier mounting solution.

Feature Summary

• High power density in a compact Half Pak module form factor
• Chassis mount design for efficient thermal management
• Replaces multiple parallel discrete diodes to simplify assembly

Applications

• High current DC power supplies
• Industrial motor drives
• Battery charging systems

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with your thermal and mechanical design requirements. Confirm that the chassis mounting interface matches your heat sink specifications. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high current handling and low forward voltage drop are critical. The Half Pak module offers superior thermal performance compared to discrete DO-5 packages. Ensure adequate heatsinking capacity is available due to the high current rating. Consider the chassis mounting requirement during PCB or enclosure layout.

Part Context

This part belongs to the 180N series of Schottky rectifiers from SMC Diode Solutions. The series is characterized by high current capabilities and robust construction for demanding power electronics environments. The Half Pak module format distinguishes it from standard through-hole or surface-mount discrete diodes.
