The IXYS MCC200-18IO1 is a high-voltage thyristor module combining two SCR elements in a standard IO1 hockey-puck-style package, rated at 200A average on-state current and 1800V repetitive peak off-state voltage (VDRM/VRRM). Designed to deliver reliable phase control and switching performance in high-power circuits, this module features low thermal resistance from junction to case and is optimized for applications where voltage transient immunity and rugged construction are non-negotiable. It conforms to established IXYS dimensional and electrical standards, enabling straightforward drop-in replacement in existing designs.

The MCC200-18IO1 is well-suited for industrial AC motor drives, soft starters, resistance heating controllers, DC power supplies, and crane or hoist drive systems. Its 1800V blocking voltage rating provides essential headroom in 690VAC and higher grid-tied applications where line transients must be safely absorbed. Power conversion equipment, electrochemical process rectifiers, and regenerative drive front-ends also represent core application areas. Engineers specifying thyristors for heavy industrial environments rely on this current and voltage class for continuous-duty performance under elevated thermal and electrical stress conditions.

Quick Reference: MCC200-18IO1

Key Features of the MCC200-18IO1:

• 1800V repetitive peak off-state and reverse voltage rating for high-line and transient-heavy grid applications
• 200A average on-state current (IT(AV)) supporting continuous heavy-duty power control cycles
• Low junction-to-case thermal resistance enabling efficient heat transfer to external heatsinks in forced-air or liquid-cooled assemblies
• IO1 isolated base package with industry-standard footprint for direct replacement and simplified mechanical integration
• High dI/dt and dV/dt capability for reliable triggering and commutation in phase-control and line-frequency switching circuits
• Gate-cathode characteristics optimized for compatibility with standard thyristor firing boards and pulse transformer drive circuits

With a current factory lead time of 99 weeks on new IXYS production, procurement teams supporting active installations or stocking repair inventory cannot afford to wait on factory orders. The MCC200-18IO1 appears frequently in legacy industrial drives, power controllers, and rectifier assemblies still in active service — equipment that cannot be taken offline for the better part of two years awaiting replacement components. ATI maintains inventory of this module as new OEM product specifically to bridge this gap, providing immediate access when a factory order simply isn't a viable option for your timeline or production schedule.
