MCD700-16IO1W

Overview

The IXYS MCD700-16IO1W is a water-cooled thyristor/diode module with a 1600 V repetitive peak off-state voltage (VDRM) and reverse voltage (VRRM). It provides a maximum average on-state current of 700 A at 42°C inlet water temperature. The device features a critical rate of rise of on-state current (di/dt) of 300 A/µs non-repetitive and 150 A/µs repetitive. Peak surge current reaches 18.2 kA, supported by an I²t capacity of 1.66×10⁶ A²s. Thermal resistance from junction to water is 0.09 K/W. Operating temperature ranges from -40°C to +125°C.

Feature Summary

• Water-cooled baseplate design for high-power thermal management
• Integrated anti-parallel diode configuration within the module
• High surge current capability with robust I²t fusing rating
• Critical dv/dt rating of 1000 V/µs for stable blocking

Applications

• Industrial motor drives and AC power control systems
• High-power DC transmission and rectification equipment
• Heavy-duty welding machines and industrial heating applications

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct voltage grade and configuration. Confirm cooling system compatibility with the specified water flow rates and inlet temperatures required to maintain the rated current capacity. Check for any updated datasheet revisions that may affect mounting force or electrical parameters.

Selection Notes

Select this component based on the required 1600 V blocking voltage and 700 A continuous current handling under defined water cooling conditions. Ensure the gate drive circuit can supply the necessary trigger current and voltage while respecting the maximum gate power limits. Evaluate the thermal impedance characteristics to match the application's duty cycle and heatsink capabilities.

Part Context

This module belongs to the IXYS M##700 series of thyristor/diode combinations. The 'MCD' designation indicates a specific internal configuration combining a thyristor and a diode in a single water-cooled package. This series is designed for high-current industrial applications requiring reliable switching and rectification capabilities.

Replacement Considerations

Direct replacements must match the 1600 V rating, 700 A current capacity, and water-cooled mounting interface. Verify pinout compatibility and thermal resistance specifications. Consult the manufacturer for updated series equivalents if the exact part number is discontinued.
