The SKM200GAR173D is a high-voltage IGBT module from SEMIKRON rated at 200A continuous collector current and 1700V blocking voltage. Engineered for demanding switching applications, this module combines low saturation voltage with fast switching characteristics and an integrated freewheeling diode, making it well suited for use in three-phase inverter topologies. Its robust DCB ceramic substrate and pressure-contact baseplate construction ensure low thermal resistance and extended operational life under continuous high-power cycling conditions found in industrial environments.

The SKM200GAR173D is widely deployed in industrial AC motor drives, regenerative braking systems, medium-voltage UPS platforms, wind turbine converters, and railway traction inverters where 1700V-class devices are required for elevated DC bus voltages. Its switching performance supports both hard-switched and soft-switched converter designs. OEM equipment manufacturers and MRO procurement teams specifying SEMIKRON modules for high-reliability power conversion stages will recognize this part across multiple platform generations in heavy industry, transportation, and renewable energy infrastructure.

Key Features of the SKM200GAR173D:

• 1700V VCES blocking voltage suitable for 1000–1200V DC bus applications with adequate voltage margin
• 200A rated continuous collector current with high peak current capability for transient load demands
• Integrated fast-recovery freewheeling diode optimized for low reverse recovery charge (Qrr) in inverter duty
• Low VCEsat design reduces conduction losses and module heat dissipation at full load
• DCB (Direct Copper Bonded) substrate provides low thermal resistance junction-to-case for high power density mounting
• Industry-standard GAR package footprint simplifies drop-in replacement in existing SEMIKRON-based power stack assemblies

With a factory lead time of 39 weeks for new production, the SKM200GAR173D presents a sourcing challenge for maintenance teams managing unplanned downtime or engineering teams working against project schedules. ATI Accurate Technology maintains active procurement channels for long lead time and allocated SEMIKRON inventory, routinely sourcing modules that are difficult to obtain through standard distribution. Whether you need a single replacement module for emergency repair or a scheduled quantity for a production build, ATI has the supplier relationships and market access to support your timeline and reduce exposure to extended lead times.
