MDD142-14N1

Overview

The MDD142-14N1 is a silicon diode module manufactured by IXYS, designed for high-power rectification applications. It features a maximum repetitive reverse voltage (Vrrm) of 1400 V and a continuous forward current (If) rating of 142 A. The device utilizes a Y4-M6 screw-mount package with a direct copper bonded Al2O3 ceramic base plate to ensure efficient thermal management. Key electrical specifications include a maximum forward voltage drop of 1.3 V and a peak non-repetitive forward surge current capability of 11.9 kA. The module operates within a junction temperature range of -40°C to +150°C and provides an isolation voltage of 3600 V.

Feature Summary

• Utilizes planar passivated chips for reliable operation
• Features a direct copper bonded Al2O3 ceramic base plate for thermal efficiency
• Provides high isolation voltage capabilities

Applications

• Industrial power supplies
• Inverter systems
• Motor drive circuits

Procurement Notes

Verify the specific suffix 'N1' against the manufacturer's latest datasheet to confirm pinout configuration and mounting hole dimensions. Ensure that the required thermal interface material is compatible with the direct copper bonded base plate surface finish. Confirm that the application circuit design accounts for the specified peak surge current limits during transient events to prevent device failure.

Selection Notes

Select this component when a robust solution for high-voltage rectification is required in industrial environments. The 142 A current rating and 1400 V blocking capability make it suitable for medium-to-high power converters. Consider the screw-mount installation method and the physical dimensions of the Y4-M6 package when designing the mechanical layout and heatsinking infrastructure for the target system.

Part Context

This part belongs to the MDD series of standard rectifier modules from IXYS. The series is characterized by its use of silicon technology and standardized international packaging formats. These modules are engineered for durability in demanding power electronics applications, offering a balance of high current handling and voltage blocking performance within a compact form factor.

Replacement Considerations

Cross-reference with other IXYS MDD series variants such as MDD142-12N1 for lower voltage requirements or MDD310-14N1 for higher current capacity. Verify that any substitute maintains the same Y4-M6 package footprint and electrical ratings to ensure compatibility with existing board layouts and thermal designs.
