The IXYS MCC19-18IO1B is a thyristor (SCR) module combining high blocking voltage capability at 1800V with a 19A current rating in a rugged, industry-standard footprint. IXYS thyristor modules in the MCC series are engineered for controlled rectification and AC power regulation where high reliability and thermal stability are critical. The isolated baseplate construction simplifies heat sink mounting and improves system safety, making this module a dependable choice for engineers designing or maintaining high-voltage power conversion equipment across a range of industrial platforms.

The MCC19-18IO1B is well suited for phase-controlled power supplies, soft-start motor drive circuits, resistance welding controllers, industrial heating systems, and AC voltage regulators. Its high off-state voltage rating makes it particularly appropriate for applications connected to 690V or higher AC bus systems where transient overvoltages are a design concern. Power electronics designers also specify this module in UPS systems, battery chargers, and crane or hoist drive controls where precise gate-triggered conduction and robust repetitive peak reverse voltage handling are essential to system uptime.

Quick Reference: MCC19-18IO1B

Key Features of the MCC19-18IO1B:

• 1800V repetitive peak off-state voltage (VDRM/VRRM) for robust high-voltage margin in 690V-class systems
• 19A average on-state current (IT(AV)) suitable for medium-power phase control and rectification stages
• Isolated copper baseplate provides electrical isolation between the thyristor junction and heat sink, simplifying system grounding and thermal management
• Low on-state voltage drop (VTM) minimizes conduction losses and reduces heat sink sizing requirements
• Industry-standard module outline ensures drop-in compatibility with existing PCB layouts and heat sink assemblies using equivalent MCC-series footprints
• Gate trigger current and holding current parameters optimized for compatibility with standard SCR gate drive circuits and firing boards

With a factory lead time of 24 weeks on new production orders, procurement teams relying solely on the manufacturer's supply chain face significant exposure to line stoppages and project delays. The MCC19-18IO1B is also positioned in a product family that includes legacy and transitional part numbers, meaning availability through standard distribution channels can be inconsistent. ATI Accurate Technology maintains independent stock of the MCC19-18IO1B specifically to bridge these gaps — serving OEM service departments, MRO buyers, and system integrators who cannot wait on extended lead times to keep critical equipment operational.
