The Infineon FS75R17KE3 is a 1700V, 75A six-pack IGBT module engineered for high-efficiency power conversion in medium-voltage industrial systems. Utilizing Infineon's IGBT3 trench and fieldstop technology, this module integrates six IGBTs with co-packaged fast recovery freewheeling diodes in a compact EconoPACK+ housing. It delivers low saturation voltage (V_CE(sat)), controlled tail current, and soft-recovery diode characteristics — critical parameters for minimizing switching losses and reducing EMI in hard-switching converter topologies operating at 1700V bus levels.

The FS75R17KE3 is well suited for medium-power industrial variable frequency drives (VFDs), regenerative drive front ends, UPS systems, solar inverters, and auxiliary traction converters. Its 1700V blocking voltage rating provides the necessary margin for 690V AC line-connected applications after accounting for line transients and overvoltage spikes. The six-pack topology simplifies PCB and busbar design by integrating a full three-phase inverter bridge into a single module, reducing assembly complexity and improving system reliability in demanding environments.

Key Features of the FS75R17KE3:

• 1700V V_CES rating with robust avalanche capability, providing reliable margin for 690V AC bus applications subject to grid transients
• IGBT3 trench and fieldstop chip technology delivering low V_CE(sat) for reduced conduction losses at full rated current
• Integrated fast-recovery anti-parallel freewheeling diodes with soft-recovery characteristics to suppress voltage overshoot during commutation
• EconoPACK+ housing with isolated AlSiC or copper baseplate options offering optimized thermal resistance (R_th(j-c)) for high-power-density designs
• Six-pack (3-phase bridge) circuit topology — all six switches in a single module for simplified drive and inverter power stage layouts
• Optimized for switching frequencies up to approximately 4–8 kHz, balancing switching loss and thermal performance in standard VFD duty cycles

With a current factory lead time of 99 weeks, procurement of the FS75R17KE3 through standard distribution channels presents a serious operational risk for MRO, production continuity, and field service applications. Drive failures and unplanned downtime cannot wait two years for new production. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time IGBT modules precisely to fill this gap — providing verified new OEM units available for immediate release without the extended wait associated with manufacturer direct or authorized distribution channels.
