Overview
The IXYS MCC255-18IO1 is a silicon thyristor module designed for high-power industrial applications. It features a WC-500 package with screw mount installation. The device supports a repetitive peak off-state voltage of 1800 V and an RMS on-state current of 255 A. It withstands a non-repetitive surge current of 4.6 kA. Key electrical parameters include a maximum gate trigger current of 150 mA and a holding current of 150 mA. The module operates within a temperature range of -40°C to +100°C.
Feature Summary
- High power handling capability with robust thermal management via the WC-500 baseplate
- Reliable triggering characteristics with defined gate control limits
- Durable construction suitable for demanding industrial environments
Applications
- Industrial motor drives and variable frequency drives
- Static power switching in high-current circuits
- Resistive load control systems
Procurement Notes
Verify component authenticity through authorized IXYS distributors or certified suppliers. Confirm RoHS compliance status and specific manufacturing lot dates upon receipt. Ensure proper handling procedures are followed due to the sensitive semiconductor nature of the module. Check for any product change notifications that may affect pinout or specifications before integration into final assemblies.
Selection Notes
Select this module when applications require 1800 V blocking voltage and 255 A continuous current capacity. The WC-500 package necessitates compatible screw-mount heatsinking solutions. Evaluate thermal resistance requirements against the system's cooling capabilities. Consider the 4.6 kA surge rating for inrush current protection needs in the target circuit design.
Part Context
This component belongs to the IXYS MCC series of thyristor modules, which are widely used in power electronics. The series offers various voltage and current ratings to suit different industrial needs. The MCC255-18IO1 specifically targets medium-to-high power applications requiring reliable SCR performance in compact form factors.
Replacement Considerations
Direct cross-compatibility with other manufacturers' parts requires careful verification of pinouts, thermal characteristics, and electrical ratings. Consult IXYS documentation for recommended equivalent models within the same family. Ensure any substitute matches the WC-500 package dimensions and mounting hole patterns.
