Overview
The 120NQ045-1 is a single Schottky barrier rectifier module manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current rating of 120 A. The component utilizes the PRM1-1 (Half Pak Module) chassis mount package, designed for high-power applications requiring robust thermal management and low forward voltage drop characteristics typical of Schottky technology.
Feature Summary
- Schottky barrier construction for fast switching and low conduction losses
- Chassis mount PRM1-1 package for efficient heat dissipation
- High current handling capability suitable for power conversion
Applications
- DC-DC converters
- Power supply units
- Solar panel rectification
Procurement Notes
Verify the specific datasheet version with SMC Diode Solutions before ordering, as product specifications may be updated. Confirm that the PRM1-1 mounting interface matches your thermal design requirements. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference part numbers carefully to avoid confusion with similar Half Pak modules.
Selection Notes
Select this component when a 45 V reverse voltage rating and 120 A continuous current are required in a chassis-mountable form factor. The PRM1-1 package offers a compact solution for high-power density designs. Consider the thermal resistance of the chassis mount for adequate heat sinking. Verify that the Schottky forward voltage characteristics meet the efficiency targets of the target circuit application.
Part Context
This device belongs to the Half Pak Module series from SMC Diode Solutions, which provides integrated solutions for high-current rectification. The PRM1-1 package integrates the semiconductor die with a metal baseplate for direct chassis mounting, simplifying assembly compared to discrete components requiring separate heatsinks.
Replacement Considerations
Consult official substitution lists from SMC Diode Solutions for verified equivalents. Ensure any replacement maintains the 120 A current rating, 45 V voltage rating, and PRM1-1 mechanical footprint. Verify electrical parameters such as forward voltage and leakage current match or exceed original specifications.
