ND411635

Overview

The ND411635 is a dual diode isolated module from the POW-R-BLOK series, manufactured by Powerex. It contains two silicon rectifier diode elements configured in a series-connected center-tap arrangement within a single phase. The device features an electrically isolated heatsink design with a metal baseplate and aluminum nitride isolator, utilizing compression-bonded elements for low thermal impedance. It is housed in a R-XUFM-X2 package with two terminals and is recognized by Underwriters Laboratories (UL).

Feature Summary

• Electrically isolated heatsinking for easy mounting on common heatsinks.
• Compression bonded elements ensure structural integrity and reliability.
• Aluminum nitride isolator provides robust electrical isolation.
• Metal baseplate construction facilitates efficient heat dissipation.

Applications

• General purpose rectification applications.
• Industrial power conversion systems requiring isolated packaging.
• Equipment mounting where components share a common heatsink.

Procurement Notes

Verify the specific voltage rating suffix associated with the ND411635 part number, as the series supports ratings up to 1700 Volts. Confirm compliance with UL recognition requirements and check for lead-free and RoHS certification status prior to procurement. Ensure the ordering suffix matches the required voltage class for the intended application.

Selection Notes

Select this module for applications requiring high current rectification with integrated isolation. The dual element configuration allows for center-tap circuit topologies. Consider the maximum non-repetitive peak forward current of 12500 A and the maximum operating temperature of 150 °C when designing thermal management solutions. Verify that the M8 threaded mounting holes align with the mechanical constraints of the assembly.

Part Context

This component belongs to the POW-R-BLOK Dual Diode Isolated Module family produced by Powerex. The series is designed for rectification tasks requiring isolated packaging. Other variants in the ND41__ series offer different current and voltage ratings, such as the ND4126 which supports up to 260 Amperes and 2400 Volts, sharing similar structural features like the aluminum nitride isolator and compression bonded elements.
