MCC56-14IO1B

Overview

The MCC56-14IO1B is a thyristor module manufactured by IXYS, belonging to the MCC56 series. It features a TO-240AA package and utilizes screw mount installation. The device is constructed using silicon technology and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a gate trigger current (Igt) of 100 mA and a maximum holding current (Ih) of 200 mA. The module is designed for high-power applications requiring robust thermal management and reliable switching performance in industrial environments.

Feature Summary

• Utilizes direct copper bonded aluminum oxide ceramic baseplate for efficient heat dissipation
• Features planar passivated chips for enhanced blocking voltage stability
• Provides electrical isolation with a rated isolation voltage of 3600 volts
• Employs vacuum and hydrogen protected welding technology for structural integrity

Applications

• AC and DC motor control systems
• Industrial heating control circuits
• Static var compensation units
• Welding machine power supplies

Procurement Notes

Verify the specific voltage rating against the datasheet, as the model number suggests a 1400V variant which may differ from standard 1200V or 1600B suffixes found in similar MCC56 listings. Confirm package authenticity and check for RoHS compliance documentation upon receipt. Ensure the supplier provides original manufacturer packaging to prevent counterfeit components.

Selection Notes

Select this module when a 56A RMS current rating and approximately 1400V blocking capability are required. Compare against MCC56-12IO8B (1200V) and MCC56-16IO1B (1600V) if exact voltage ratings are flexible. Ensure the cooling system supports the thermal resistance specifications for the TO-240AA package under continuous load conditions.

Part Context

This component is part of the IXYS MCC56 family of thyristor modules, designed for medium to high-power industrial applications. The series typically includes variants with different voltage ratings such as 1200V and 1600V. The MCC56 designation indicates a 56A current class, while the suffix denotes specific voltage and terminal configurations within the product line.

Replacement Considerations

Direct substitutes include MCC56-12IO8B for 1200V applications and MCC56-16IO1B for 1600V requirements, provided the voltage margin allows. Verify pinout compatibility and thermal characteristics before substitution. Cross-referencing with other manufacturers' TO-240AA SCR modules requires careful evaluation of forward voltage drop and gate trigger parameters.
