The device supports junction temperatures up to 150°C and utilizes chassis mount technology for efficient thermal dissipation.

Feature Summary

• High-power Half Pak module design
• Chassis mount construction
• Schottky barrier rectification

Applications

• Chassis mount power supply applications
• High current rectification circuits
• Industrial power conversion systems

Procurement Notes

Verify the specific suffix 'R-1' against the manufacturer's official datasheet to confirm exact electrical characteristics and pinout configuration. Ensure the procurement documentation explicitly references the PRM1-1 package type to avoid confusion with standard discrete diodes or alternative mounting styles.

Selection Notes

Select this component when high current handling at low voltage drops is required in a compact form factor. The Half Pak module offers superior thermal performance compared to parallel discrete DO-5 packages, simplifying heatsinking requirements while maintaining reliability under continuous load conditions.

Part Context

This part belongs to SMC Diode Solutions' single diode lineup, specifically designed as a replacement for multiple parallel DO-5 configurations. The PRM1-1 packaging provides a lower profile and easier mounting solution for industrial applications requiring robust rectification capabilities.

Replacement Considerations

Officially documented as a replacement for three parallel DO-5 diodes. Verify mechanical footprint compatibility before substitution.
