Overview
The 181NQ035-1 is a Schottky barrier rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 35 V and an average forward rectified current of 180 A. The device utilizes the PRM1-1 (Half Pak Module) chassis mount package. Key electrical characteristics include a maximum forward voltage of 660 mV at 180 A and a maximum non-repetitive peak surge forward current rating of 1200 A. It operates within a junction temperature range of -55°C to 175°C.
Feature Summary
- Schottky technology ensures low forward voltage drop for high efficiency.
- Chassis mount PRM1-1 module design facilitates easy installation.
- High thermal performance supports operation up to 175°C junction temperature.
Applications
- High current DC power supplies
- Free wheeling diodes in motor drives
- Polarity protection circuits
Procurement Notes
Verify the specific suffix and package variant against the official datasheet before ordering. Confirm that the chassis mounting requirements align with the system design. Ensure compliance with RoHS standards if required by the project specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component for applications requiring high current handling in a compact chassis-mount form factor. The Schottky construction minimizes switching losses compared to standard recovery diodes. Evaluate the thermal management capabilities of the host system to maintain junction temperatures within the specified 175°C limit under full load conditions.
Part Context
This component belongs to the 181NQ series of Schottky rectifiers from SMC Diode Solutions. These devices are designed as replacements for multiple parallel DO-5 diodes, offering a lower profile and easier mounting solution. The Half Pak Module format integrates high-power capability into a standardized chassis mount package suitable for industrial environments.
Replacement Considerations
Publicly confirmed substitute part numbers include 181NQ040-1 and 181NQ045-1 from the same manufacturer series. These alternatives share the same PRM1-1 package and mechanical footprint but offer higher reverse voltage ratings of 40 V and 45 V respectively. Verify thermal and electrical compatibility before substitution.
