ND410826

Overview

The ND410826 is a POW-R-BLOK dual diode isolated module manufactured by Powerex Inc. It features an electrically isolated heatsink design utilizing aluminum nitride insulation and compression-bonded elements on a metal baseplate for low thermal impedance. The module contains two silicon rectifier diode elements configured in a series-connected, center-tap arrangement. It is designed for applications requiring rectification with easy mounting to common heatsinks. The device has been tested and recognized by Underwriters Laboratories (UL).

Feature Summary

• Electrically isolated heatsinking capability for simplified assembly.
• Aluminum nitride isolator ensures dielectric strength between terminals and base.
• Compression bonded elements provide robust mechanical stability.
• Metal baseplate construction facilitates efficient heat dissipation.

Applications

• Industrial rectification circuits requiring isolated packaging.
• Power supplies utilizing common heatsink mounting configurations.
• Equipment needing UL recognized components for safety compliance.

Procurement Notes

Verify the specific voltage rating suffix associated with the ND410826 part number, as the POW-R-BLOK series spans multiple voltage classes. Confirm that the required reverse voltage matches the component's specification before procurement. Ensure the mounting interface aligns with the standard M8 thread dimensions typical of this module family.

Selection Notes

Select this module when high current rectification and electrical isolation from the heatsink are required simultaneously. The dual element configuration supports center-tapped topologies. Verify that the thermal management system can handle the power dissipation inherent to the compression-bonded silicon elements within the aluminum nitride insulated package.

Part Context

This component belongs to the POW-R-BLOK family of dual diode modules produced by Powerex Inc.
