Overview
The 180NQ040-1 is a single Schottky diode module manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage of 40 V and an average rectified current rating of 180 A. The forward voltage drop is specified at a maximum of 600 mV when conducting 180 A. The device utilizes PRM1-1 (Half Pak Module) packaging and is designed for chassis mounting. It exhibits fast recovery characteristics with a switching time of less than or equal to 500 ns.
Feature Summary
- Schottky barrier technology for low forward voltage drop
- High current capacity suitable for power conversion
- Robust chassis mount construction for thermal management
Applications
- DC-DC converters
- Power supply rectification
- Free-wheeling diodes in motor drives
Procurement Notes
Verify the specific datasheet version from SMC Diode Solutions prior to procurement, as product specifications may be updated. Confirm that the PRM1-1 package dimensions align with your chassis mounting hardware requirements. Ensure thermal interface materials are compatible with the module's base plate to maintain optimal heat dissipation during operation at rated currents.
Selection Notes
Select this component for applications requiring high surge current handling and low conduction losses at moderate reverse voltages. The 40 V rating limits its use to low-voltage systems. Consider the 180 A continuous current capability against your load profile. The Half Pak form factor requires dedicated heatsinking infrastructure compared to standard discrete packages.
Part Context
This part belongs to the 180NQ series of Schottky rectifiers from SMC Diode Solutions. These modules are engineered for high-efficiency power processing where speed and thermal performance are critical. The series typically offers various voltage ratings while maintaining consistent current capabilities across different package variants within the Half Pak family.
Replacement Considerations
Direct substitutes include the 180NQ035/R-1 and 180NQ045/R-1 from the same manufacturer, which share identical mechanical and electrical profiles except for their reverse voltage ratings.
