The IXYS MCC26-14IO8B is a thyristor (SCR) module rated for 26A average on-state current and a 1400V repetitive peak off-state voltage (VDRM). Housed in a standard power module package, this device integrates a single SCR configuration with isolated baseplate construction to simplify heatsink mounting and system assembly. It is engineered for stable gate sensitivity, low on-state voltage drop, and high surge current capability — characteristics that make it a dependable choice for phase control, soft-start, and AC power regulation circuits operating in harsh industrial environments.

The MCC26-14IO8B sees broad use across industrial power conversion equipment including AC motor soft starters, resistance heating controllers, DC drive front ends, welding power supplies, and crane or hoist drive systems. Its high blocking voltage rating makes it well suited for 480V and 600V three-phase line applications where transient overvoltages demand substantial voltage margin. Power electronics engineers also specify this module in UPS front-end rectifiers, transformer tap changers, and controlled rectifier bridges where precise firing angle control and thermal reliability are critical to uptime.

Key Features of the MCC26-14IO8B:

• 1400V repetitive peak off-state voltage (VDRM) provides robust margin for 480V and 600V three-phase applications subject to line transients
• 26A average on-state current (IT(AV)) with high surge current (ITSM) capability for reliable operation under overload and fault conditions
• Isolated copper baseplate construction allows direct mounting to heatsink without additional insulating hardware, reducing thermal resistance and assembly complexity
• Low and consistent gate trigger current (IGT) specifications ensure reliable firing across temperature extremes, simplifying gate drive circuit design
• Compact industry-standard module footprint enables drop-in replacement in existing PCB or busbar assemblies without mechanical redesign
• Manufactured to IXYS quality and process standards with traceability documentation suitable for MRO, OEM production, and field service applications

With a current factory lead time of 35 weeks for new production orders, procurement teams relying on the MCC26-14IO8B for scheduled maintenance, emergency repair, or production line continuity cannot afford to wait. IXYS thyristor modules in the MCC series are also increasingly difficult to source through standard distribution channels as product lines consolidate following Littelfuse's acquisition of IXYS. ATI Accurate Technology maintains verified stock of hard-to-find and long-lead-time IXYS power modules specifically to support customers who cannot absorb extended procurement delays.
