The Mitsubishi RM15TA-H is a diode/thyristor (SCR) combination module engineered for industrial power electronics applications where controlled rectification and phase management are essential. This module integrates thyristor and diode elements within a single compact package, reducing assembly complexity while maintaining the thermal and electrical performance required in harsh operating environments. Designed to Mitsubishi's rigorous quality standards, the RM15TA-H is a proven component in variable-speed drives, power conversion systems, and industrial automation equipment worldwide.

The RM15TA-H is widely deployed across heavy industrial sectors including steel processing, paper and pulp machinery, crane and hoist drive systems, HVAC variable frequency equipment, and marine propulsion controls. Its diode/thyristor topology makes it especially well-suited for three-phase half-wave or mixed-bridge rectifier configurations used in DC motor drives and AC/DC converters. Maintenance engineers maintaining legacy equipment and OEM designers specifying reliable phase-control modules consistently rely on the RM15TA-H for its consistent switching characteristics and long service life in continuous-duty applications.

Key Features of the RM15TA-H:

• Integrated diode and thyristor elements in a single isolated-base module package, simplifying PCB and heatsink mounting in drive assemblies
• Isolated copper base plate provides effective thermal transfer to external heatsinks, supporting reliable operation under continuous load cycles
• Gate-controlled thyristor element enables precise phase-angle firing for regulated DC output voltage in controlled rectifier circuits
• Designed for compatibility with standard Mitsubishi RM-series mounting footprints, facilitating direct replacement in existing equipment without mechanical redesign
• Suitable for repetitive surge current conditions typical in motor starting, inductive load switching, and industrial soft-start applications
• Manufactured under Mitsubishi's established quality control processes, ensuring consistent forward voltage drop, holding current, and gate trigger characteristics across production lots

With a factory production lead time of 34 weeks, procuring the RM15TA-H through standard distribution channels can mean extended equipment downtime—an unacceptable outcome in production-critical environments. Obsolescence and allocation pressures on Mitsubishi power modules make spot availability increasingly difficult to secure. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time modules like the RM15TA-H specifically to support maintenance teams and procurement professionals who cannot afford to wait. Whether you need a single replacement or a strategic buffer stock, ATI is positioned to fulfill your requirement immediately from verified new OEM inventory.
