The Mitsubishi RM30TB-H is a hybrid diode/thyristor module engineered for high-reliability operation in industrial power electronics systems. As part of Mitsubishi's RM-series power module lineup, this device integrates thyristor (SCR) and diode elements within a single isolated package, simplifying board layout and thermal management. The module is constructed for robust performance in AC/DC conversion topologies where controlled rectification is required, delivering consistent switching characteristics and low on-state losses critical to system efficiency and long service life in harsh industrial environments.

The RM30TB-H is well suited for a broad range of industrial applications including AC motor drives, soft starters, DC bus power supplies, regenerative drive systems, and industrial UPS equipment. Its compact module form factor makes it a practical choice for OEM equipment builders and MRO replacement in CNC machinery, crane and hoist controls, press drives, and process line equipment. Engineers specifying controlled rectifier stages in three-phase input designs will find the RM30TB-H a reliable building block where rugged thyristor gating and fast diode recovery are both required in a thermally optimized package.

Quick Reference: RM30TB-H

Key Features of the RM30TB-H:

• Integrated diode and thyristor (SCR) elements in a single isolated power module package for simplified converter design
• 30A continuous current rating suitable for mid-range industrial drive and rectifier applications
• Isolated copper base plate construction for direct heatsink mounting and effective thermal dissipation
• Compact RM-series footprint compatible with standard Mitsubishi module mounting hardware and heatsink platforms
• Low on-state voltage drop across both thyristor and diode elements, supporting high-efficiency rectification stages
• Gate trigger characteristics optimized for reliable phase-control firing in industrial SCR drive circuits

With a current factory lead time of 43 weeks on new production, procurement professionals and maintenance teams cannot rely on ordering direct when equipment is down or a scheduled outage is approaching. The RM30TB-H has seen reduced availability through standard distribution channels, making it a functionally obsolete or allocation-constrained component for many buyers. ATI Accurate Technology specializes in exactly these situations — maintaining stock of long-lead-time and hard-to-find Mitsubishi power modules so your repair, retrofit, or production line schedule is not held hostage to a nearly year-long factory queue.

ATI Accurate Technology is located in Palmetto, Florida and ships the RM30TB-H same-day on orders placed before 5PM EST. We supply new OEM parts to maintenance engineers, equipment rebuilders, and procurement teams across North America.
