The Toshiba MG400J2YS50 is a high-voltage, high-current IGBT module engineered for performance-critical power electronics applications. Rated at 400A continuous collector current and a 2500V collector-emitter voltage class, this module is built to handle the rigorous demands of industrial and traction power systems. The MG400J2YS50 features a co-packaged freewheeling diode, reducing external component count and simplifying converter design. Its isolated baseplate construction supports direct heatsink mounting, enabling effective thermal management in high-power inverter and converter topologies.

The MG400J2YS50 is a proven choice for medium-voltage industrial drives, AC motor controllers, traction inverters, induction heating systems, UPS platforms, and grid-tied power conversion equipment. Engineers specifying devices for steel mill drives, mining equipment, rail traction systems, or large-scale renewable energy inverters will recognize this voltage and current class as a workhorse of heavy industrial power electronics. Its combination of voltage blocking capability and current handling makes it suitable for both two-level and multilevel converter architectures operating at medium voltage levels.

Key Features of the MG400J2YS50:

• 400A continuous collector current (IC) for high-power switching stages
• 2500V collector-emitter voltage (VCES) rating supporting medium-voltage bus architectures
• Integrated co-packaged freewheeling diode for complete half-bridge or chopper circuit implementation
• Isolated copper baseplate for efficient thermal coupling to external heatsinks
• Low gate charge and optimized switching characteristics reduce switching losses at industrial operating frequencies
• Standard Toshiba power module footprint for drop-in replacement compatibility in existing drive platforms

With a current factory lead time of 99 weeks, sourcing the MG400J2YS50 through normal distribution channels presents a serious risk to production schedules and equipment uptime. Maintenance teams facing unplanned failures and procurement professionals managing spares inventory cannot afford to wait nearly two years for new production. Obsolescence pressure on legacy drive platforms further compounds the challenge. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time power semiconductors precisely for these situations, giving you a direct path to fulfillment without the factory queue.
