MDMA35P1200TG

Overview

The MDMA35P1200TG is a high-power general-purpose rectifier manufactured by IXYS. It features a peak repetitive reverse voltage (Vrrm) of 1200 V and a maximum continuous forward current (If) of 35 A. The device utilizes a panel mount installation style within a TO-240 package configuration, which includes seven pins. Key electrical characteristics include a peak non-repetitive forward surge current (Ifsm) of 700 A and a maximum forward voltage drop (Vf) of 1.65 V at rated current. The component operates reliably across a temperature range from -40°C to +150°C junction temperature, with a typical peak reverse leakage current of 10 µA.

Feature Summary

• High-voltage capability designed for demanding power conversion environments
• Robust thermal management through dedicated panel mounting interface
• Enhanced surge current handling for transient protection applications

Applications

• Industrial motor drive rectification circuits
• Uninterruptible power supply (UPS) input stages
• Welding machine power supplies

Procurement Notes

Verify the specific suffix 'TG' against the manufacturer's latest datasheet to confirm lead-free compliance and RoHS status. Ensure the TO-240 package dimensions match your mechanical constraints. Confirm that the 1200V rating aligns with your system's peak inverse voltage requirements. Cross-reference the pinout diagram with your PCB or chassis layout design before finalizing procurement orders.

Selection Notes

Select this component when a single-phase rectifier requires 1200V blocking capability with moderate current handling. Compare the 35A continuous rating against your RMS load requirements. Consider the TO-240 package size relative to available heatsinking space. Evaluate the 1.65V forward voltage impact on overall system efficiency compared to lower Vf alternatives if thermal budget allows.

Part Context

This part belongs to IXYS's MDMA series of high-power diodes, engineered for industrial and traction applications. The series emphasizes reliability under high-stress conditions. The TO-240 package provides a standardized footprint for panel mounting, facilitating integration into larger power modules or chassis-based systems where direct thermal conduction to a cold plate is required.

Replacement Considerations

Check for direct cross-references in IXYS catalogs. Verify equivalent voltage and current ratings from other manufacturers like Vishay or Microchip. Ensure pin compatibility and thermal resistance values are comparable before substituting.
