The Toshiba MG150Q2YS50 is a 150A, 500V IGBT power module engineered for demanding switching applications where thermal stability, low saturation voltage, and consistent gate drive characteristics are essential. Designed within Toshiba's proven Q-series module platform, the MG150Q2YS50 integrates insulated gate bipolar transistor technology with a robust housing suitable for high-frequency pulse-width modulation (PWM) operation. Engineers specifying this device benefit from a well-characterized switching profile that supports both hard and soft-switching topologies in industrial power electronics systems.

The MG150Q2YS50 is widely deployed in AC motor variable frequency drives (VFDs), industrial inverters, UPS systems, servo amplifiers, and regenerative braking circuits. Its voltage and current ratings make it a strong fit for mid-range industrial machinery including CNC equipment, HVAC compressor drives, elevator controls, and welding power supplies. OEM equipment manufacturers and MRO maintenance teams alike rely on this module for both new equipment builds and field replacement of aging power stages in installed base equipment across manufacturing, energy, and process industries.

Key Features of the MG150Q2YS50:

• 150A continuous collector current with 500V collector-emitter voltage rating for mid-power industrial switching applications
• Low V_CE(sat) characteristics minimize conduction losses and reduce thermal stress on the module during sustained operation
• Integrated free-wheeling diodes provide full inductive load protection within a compact, self-contained module footprint
• Isolated baseplate construction supports direct mounting to heatsinks, simplifying thermal management in high-density drive assemblies
• Optimized gate charge profile enables stable switching performance across a broad range of PWM frequencies typical in VFD and inverter designs
• Compatible with standard Toshiba Q-series module footprint, facilitating direct form-fit-function replacement in existing equipment

With a factory lead time of 99 weeks, the MG150Q2YS50 is effectively unavailable through standard distribution for any project or repair requiring near-term delivery. For maintenance engineers managing unplanned equipment failures, or procurement teams supporting production lines that cannot absorb months-long downtime, that lead time is not a viable option. ATI Accurate Technology specializes in exactly this scenario — stocking hard-to-find, long-lead-time, and obsolete power semiconductors so that critical repairs and builds are not held hostage to manufacturer production schedules. Our inventory is verified new OEM product, not surplus of unknown provenance.

ATI Accurate Technology is located in Palmetto, Florida and ships same-day on orders received before 5PM EST. Whether you need a single module for emergency maintenance or a larger quantity for a scheduled overhaul or production run, we offer competitive volume pricing.
