Overview
The IXYS MCC255-16IO1 is a dual thyristor module designed for high-power industrial applications. It features a TO-240AA package with seven pins and panel mounting configuration. The device supports a repetitive peak reverse voltage of 1600 V and an RMS on-state current of 255 A. Non-repetitive surge current capability reaches 8.6 kA. Gate triggering parameters include a maximum gate trigger current of 150 mA and a maximum gate trigger voltage of 2.5 V. The module operates within a temperature range of -40°C to +125°C, with a holding current maximum of 200 mA and a peak on-state voltage of 1.25 V.
Feature Summary
- Dual SCR configuration in a single isolated module
- High surge current handling capability
- Robust thermal performance for industrial environments
Applications
- Industrial motor drives
- Power supply systems
- Welding equipment
Procurement Notes
Verify the specific datasheet revision and manufacturer documentation before integration. Confirm that the TO-240AA mechanical dimensions match the target heatsink interface. Ensure gate drive circuits comply with the specified 150 mA trigger current limits. Validate thermal management strategies against the 125°C maximum junction temperature rating.
Selection Notes
Select this component when a dual thyristor arrangement is required in a compact form factor. Compare the 255 A RMS current rating against load requirements. Consider the 1600 V blocking voltage for system insulation needs. Evaluate the TO-240AA package for compatibility with existing PCB or busbar layouts.
Part Context
This part belongs to the IXYS MCC series of silicon controlled rectifier modules. The series is engineered for robust power switching in demanding electrical environments. The MCC255-16IO1 represents a mid-range current option within the family, balancing conduction losses with surge capacity.
Replacement Considerations
Direct cross-compatibility with other manufacturers requires careful verification of pinout, thermal resistance, and electrical characteristics. Review datasheets for equivalent current ratings and package dimensions. No official substitutes are listed by the manufacturer.
