MDMA85P1600TG

Overview

The MDMA85P1600TG is a silicon SCR module manufactured by IXYS, designed for high-power line frequency applications. It features a peak repetitive reverse voltage (Vrrm) of 1600 V and a maximum continuous forward current (If) of 85 A. The device utilizes a TO-240 package with seven pins and supports panel mounting. Key electrical characteristics include a peak non-repetitive forward surge current (Ifsm) of 3.03 kA, a maximum forward voltage (Vf) of 1.43 V, and a peak reverse current (Ir) of 3.5 mA. Operating temperatures range from -40°C to 150°C.

Feature Summary

• High-voltage capability with 1600 V blocking rating
• Robust surge handling with 3.03 kA peak non-repetitive current
• Integrated thermal management via panel mount design

Applications

• Industrial motor drives
• Power supply rectification
• Welding equipment

Procurement Notes

Verify the specific datasheet revision and pinout configuration against your schematic before ordering. Confirm that the TO-240 mechanical dimensions match your heatsink interface requirements. Ensure the 1600 V rating provides adequate margin for your circuit's transient voltages. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a single-phase or bridge rectifier application requires 1600 V blocking and up to 85 A continuous current in a compact form factor. The TO-240 package offers a balance between power density and ease of thermal attachment compared to larger modules. Consider the 1.43 V forward drop for efficiency calculations at full load conditions.

Part Context

This part belongs to IXYS's MDMA series of thyristor modules, which are engineered for demanding industrial environments. The series typically includes variants with different current ratings but shares common packaging and voltage classes. These modules are widely used in AC/DC conversion stages where reliability under high stress is critical.

Replacement Considerations

Direct substitutes may include other IXYS models within the MDMA family with similar voltage and current ratings, such as MDMA65P1600TG or MDMA140P1600TG, provided the current capacity meets the specific application needs. Cross-brand replacements require careful verification of pin compatibility and thermal resistance values.
