The Infineon FS300R17KE3 is a 300A, 1700V six-pack IGBT module built on Infineon's IGBT3 trench-fieldstop chip technology. Housed in a compact EconoDUAL 3 or equivalent high-density package, this module integrates six IGBT switches with freewheeling diodes optimized for low conduction and switching losses at elevated junction temperatures. The FS300R17KE3 targets high-efficiency, high-reliability operation in three-phase inverter topologies where thermal headroom and switching performance are critical design constraints. Its 1700V voltage class makes it particularly suited for medium-voltage bus architectures common in industrial and traction environments.

The FS300R17KE3 sees broad deployment across industrial motor drives, regenerative elevator drives, wind turbine converters, solar string inverters, UPS systems, and rail traction inverters. Any application operating from a medium-voltage DC bus — typically 800V to 1200V — benefits from the 1700V blocking voltage headroom this module provides. Its thermally optimized base plate and industry-standard footprint simplify drop-in replacement of aging or failed modules in legacy equipment where downtime costs are high and maintaining uptime is non-negotiable for operations teams.

Key Features of the FS300R17KE3:

• 1700V VCES collector-emitter blocking voltage with 300A continuous collector current rating for medium-voltage inverter designs
• IGBT3 trench-fieldstop cell technology delivering reduced VCEsat and optimized switching energy losses (Eon/Eoff) across the operating temperature range
• Integrated fast-recovery anti-parallel freewheeling diodes with soft reverse recovery characteristics to minimize EMI and voltage overshoot
• Maximum junction temperature (Tj max) of 150°C enabling higher power density and improved thermal cycling reliability
• Industry-standard six-pack (three-phase bridge) configuration simplifies PCB layout and gate driver design in AC drive applications
• Low stray inductance package design supports high switching frequencies and reduces snubber requirements in converter builds

With a current factory lead time of 99 weeks, the FS300R17KE3 is effectively unavailable through standard distribution channels for nearly two years. For maintenance engineers performing emergency repairs or procurement teams managing capital equipment lifecycles, that lead time is operationally unacceptable. ATI Accurate Technology maintains inventory of hard-to-find, long-lead-time, and obsolete IGBT modules specifically to close this gap. Buying from ATI eliminates the queue entirely — parts ship the same day from verified new OEM stock, keeping critical systems running without extended downtime or costly equipment substitutions.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, specializing in IGBTs, thyristors, diodes, and rectifier modules. We stock the FS300R17KE3 new and ready to ship same-day on orders placed before 5PM EST. Volume pricing is available for MRO stocking orders and project quantities.
