MDD142-16N1

Overview

The IXYS MDD142-16N1 is a dual diode module designed for high-power applications. It features a nominal forward current of 165 A and a maximum repetitive peak reverse voltage of 1600 V. The device utilizes a Y4-M6 screw mount package with a direct copper bonded Al2O3 ceramic base plate. Electrical characteristics include a maximum forward voltage of 1.05 V at rated current. The module supports an operating temperature range from -40°C to +125°C and provides an isolation voltage of 3600 V.

Feature Summary

• Planar passivated chips ensure reliable operation under high-stress conditions
• Direct copper bonded Al2O3 ceramic base plate optimizes thermal dissipation
• International standard package facilitates mechanical integration in power systems

Applications

• Industrial motor drives
• Uninterruptible power supplies (UPS)
• Power factor correction circuits

Procurement Notes

Verify the specific datasheet version prior to ordering, as product change notifications may alter physical dimensions or electrical tolerances. Confirm that the Y4-M6 mounting interface matches the target heatsink design. Ensure thermal interface material selection aligns with the specified maximum junction temperature limits to maintain long-term reliability in high-current environments.

Selection Notes

Select this component when designing circuits requiring high voltage blocking capability combined with substantial continuous current handling. The 1600 V rating suits medium-voltage industrial applications. Consider the 1.05 V forward voltage drop for efficiency calculations. The screw-mount configuration requires appropriate torque specifications during assembly to ensure consistent thermal contact and electrical connection stability.

Part Context

This module belongs to the MDD series of discrete power diodes manufactured by IXYS. The series targets robust power conversion needs where standard packages cannot handle the required current densities. The MDD142 variant specifically addresses applications demanding higher current capacity than lower-rated siblings while maintaining compact form factors suitable for dense power electronics layouts.

Replacement Considerations

Cross-reference with other manufacturers' 165A 1600V dual diode modules featuring Y4-M6 packages. Verify pinout compatibility and thermal resistance values before substitution. Ensure replacement parts meet identical isolation voltage requirements for safety compliance.
