MCC56-16IO8B

Overview

The MCC56-16IO8B is a dual thyristor module manufactured by IXYS, designed for high-voltage and high-current industrial applications. It features a TO-240AA screw-mount package with a silicon construction. The device supports a maximum repetitive peak reverse voltage of 1600V and an on-state current rating of 16A. Key electrical parameters include a gate trigger current of 10mA and a holding current maximum of 200mA. The module operates within a temperature range of -40°C to +100°C and provides direct copper-bonded alumina ceramic baseplate insulation.

Feature Summary

• Dual thyristor configuration ensuring reliable power switching in demanding environments
• Direct copper-bonded Al2O3 ceramic baseplate for efficient thermal management
• Planar passivated chips providing robust electrical isolation and blocking capabilities
• Screw-mount installation design compatible with standard industrial heat sinks

Applications

• AC/DC motor control systems
• Industrial heating control circuits
• Variable frequency drives (inverters)
• Uninterruptible power supply (UPS) units

Procurement Notes

Verify the specific suffix IO8B against official IXYS datasheets to confirm pinout and internal circuit topology, as ordering suffixes define functional variations. Ensure compatibility with existing thermal interface materials and mounting hardware specifications. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated equipment assemblies.

Selection Notes

Select this component when a dual SCR solution is required for phase control or rectification tasks involving voltages up to 1600V. The TO-240AA package suits applications requiring screw-mount thermal dissipation rather than PCB soldering. Evaluate the 16A current rating against peak load requirements to ensure adequate safety margins for continuous operation under specified ambient temperatures.

Part Context

This part belongs to the MCC series of discrete semiconductor modules from IXYS, specialized for power electronics. The series utilizes vacuum-hydrogen protected welding technology for enhanced durability. It serves as a critical switching element in medium-power industrial converters, offering a balance between high voltage blocking capability and manageable gate drive requirements.

Replacement Considerations

Cross-reference with other IXYS MCC series variants such as MCC56-18IO8B for current adjustments. Verify mechanical footprint compatibility with alternative manufacturers' TO-240AA packages before substitution. Electrical parameter matching for Vdrm and Iot is essential to maintain system performance integrity.
