MCO450-22IO1

Overview

The IXYS MCO450-22IO1 is a high-power single thyristor module featuring a direct copper bonded Al2O3 ceramic structure with a copper base plate. It provides a maximum repetitive peak reverse voltage of 2200 V and an RMS on-state current rating of 750 A at a case temperature of 25°C. The device incorporates planar passivated chips and offers an isolation voltage of 3600 V~. Key electrical characteristics include a gate trigger delay time of 2 µs, a turn-off time of 350 µs, and a thermal resistance from junction to case of 0.072 K/W under DC conditions.

Feature Summary

• Direct Copper Bonded Al2O3 ceramic construction with a copper base plate for enhanced thermal management
• Planar passivated chips designed to improve temperature and power cycling performance
• Keyed gate/cathode twin pins for secure terminal connection

Applications

• Motor control systems
• Soft starters
• Power converters
• Industrial furnace heat and temperature control
• Lighting control

Procurement Notes

Verify the specific voltage suffix (22) corresponds to the required 2200 V rating against the official datasheet table. Confirm that the keyed twin-pin configuration matches the intended circuit board layout. Ensure mounting torque specifications are strictly adhered to during installation to maintain mechanical integrity and thermal contact.

Selection Notes

Select this component when high surge current capability and robust thermal cycling performance are required. The 2200 V rating suits applications demanding higher voltage margins than the 2000 V variant. Evaluate the 750 A RMS current capacity against the system's continuous load requirements and ambient temperature derating curves.

Part Context

This module belongs to the MCO 450 series of high-power single thyristors manufactured by IXYS. The series utilizes Direct Copper Bonded technology to provide superior thermal conductivity and mechanical stability compared to standard ceramic substrates.
