IXYS MCC95 Series Technical Notes

The IXYS MCC95 series comprises phase-controllable thyristor (SCR) modules rated at 95 A average on-state current, designed for deployment in heavy industrial power conversion systems. These modules are installed across global heavy industry sectors including chemical processing plants, nuclear power auxiliary systems, oil refineries, steel rolling mills, and marine drive systems. The MCC95 platform operates within the standard IXYS stud-and-flat-base package format, enabling direct interchangeability with legacy rectifier assemblies. Repetitive peak off-state voltage ratings span from 800 V to 1800 V depending on the specific variant, making the series applicable to both 400 V and 690 V AC bus architectures. The series is manufactured to IEC 60747-6 standards and is compatible with standard thyristor gate drive circuits operating at 100–200 mA gate trigger current.

The Evolution of MCC95 Architecture

The MCC95 series belongs to IXYS's second-generation stud-mount thyristor module family, succeeding earlier discrete stud-mount SCR devices that required individual heatsink mounting and external snubber networks. The MCC95 package integrates two thyristors in an anti-parallel (AC switch) or series (DC switch) configuration within a single isolated base module, reducing assembly footprint by approximately 40% compared to discrete implementations.
