ND411235

Overview

The ND411235 is a dual diode isolated module manufactured by Powerex Inc. It belongs to the POW-R-BLOK series, designed for rectification applications requiring isolated packaging. The device features two silicon rectifier diode elements configured in a series-connected center-tap arrangement within a single phase. It utilizes an R-XUFM-X2 package with two terminals and an isolated case connection for mounting on common heatsinks. The module supports a maximum non-repetitive peak forward current of 12500 A and operates at temperatures up to 150 °C.

Feature Summary

• Electrically isolated heatsinking capability for simplified thermal management
• Dual diode configuration in a compact isolated module format
• UL recognized certification for safety compliance

Applications

• General purpose rectification circuits
• Industrial power conversion systems
• Applications requiring isolated component mounting on shared heatsinks

Procurement Notes

Verify the specific voltage rating suffix associated with the ND411235 part number, as the POW-R-BLOK series spans 600 to 1700 Volts. Confirm the package outline drawing matches the required mechanical footprint. Ensure the application current does not exceed the specified 12500 A non-repetitive peak limit. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this module when high current rectification and electrical isolation are required in a single package. The center-tap configuration suits specific transformer coupling needs. Verify that the operating temperature range up to 150 °C aligns with the system's thermal environment. Consider the isolated case design for ease of integration into existing heatsink infrastructure without additional insulators.

Part Context

This component is part of Powerex's POW-R-BLOK family of dual diode modules. These modules are engineered for robust performance in demanding power electronics environments. The series offers various voltage ratings while maintaining consistent current handling capabilities and isolation standards across different models.

Replacement Considerations

Substitute parts must match the dual diode center-tap configuration, isolated case type, and similar current/voltage ratings. Verify pinout compatibility and mechanical dimensions before replacement.
