MDD172-14N1

Overview

The MDD172-14N1 is a silicon rectifier diode module manufactured by IXYS. It features a single-phase, two-element configuration with a maximum repetitive reverse voltage of 1400V and an average forward current rating of 172A. The device utilizes a Y4-M6 screw-mount package designed for high-power applications. Key electrical characteristics include a maximum forward voltage drop of 1.15V at rated current. The module supports a junction temperature range from -40°C to +150°C, ensuring reliable operation in demanding thermal environments.

Feature Summary

• High current capacity suitable for industrial power conversion
• Robust screw-mount construction for secure mechanical attachment
• Wide operating temperature range for harsh environment reliability

Applications

• Industrial motor drives
• DC power supplies
• Inverter circuits

Procurement Notes

Verify the specific manufacturer source, as IXYS discrete semiconductor modules are often distributed under Littelfuse branding following corporate acquisitions. Confirm that the ordering suffix matches the required voltage and current ratings exactly. Ensure compliance with RoHS directives if applicable to your assembly process. Check for any recent product change notifications regarding material or manufacturing site updates before finalizing procurement.

Selection Notes

Select this component when a 172A continuous current rating and 1400V blocking capability are required in a compact screw-mount form factor. The Y4-M6 package offers a balance between thermal performance and mounting simplicity compared to larger water-cooled alternatives. Consider the 1.15V forward voltage drop for efficiency calculations in low-voltage, high-current output stages where conduction losses are significant.

Part Context

This module belongs to the MDD series of high-power silicon rectifiers designed for robust industrial use. The series provides various current and voltage combinations to suit different power levels. The MDD172-14N1 specifically targets applications requiring moderate-to-high current handling with standard air-cooling solutions, fitting into the mid-range of the IXYS/Littelfuse discrete diode portfolio.

Replacement Considerations

Direct substitutes within the same family include the MDD172-16N1 (1600V) or MDD172-18N1 (1800V) if higher voltage margins are needed. For lower voltage requirements, the MDD172-08N1 or MDD172-12N1 may be considered, provided the reverse voltage rating remains sufficient for the circuit application.
