The Infineon FP40R12KE3G is a 1200V, 40A IGBT module engineered for high-efficiency power switching in industrial-grade systems. Based on Infineon's third-generation IGBT chip technology, this module offers an optimized balance of switching speed and conduction losses, making it well-suited for converters and inverters where thermal performance and switching reliability are critical. The module integrates fast recovery freewheeling diodes and is housed in a standard footprint package, simplifying board-level integration and replacement in existing designs.

The FP40R12KE3G sees wide deployment across variable frequency drives (VFDs), servo drive systems, UPS inverters, induction heating equipment, and industrial welding power supplies. Its 1200V blocking voltage provides adequate design margin for 480V three-phase AC bus applications, while the 40A current rating suits mid-power drive stages and auxiliary converter circuits. Engineers specifying parts for elevator drives, HVAC compressor controls, or regenerative braking systems will find this module's characteristics directly applicable to those load profiles.

Quick Reference: FP40R12KE3G

Key Features of the FP40R12KE3G:

• 1200V collector-emitter breakdown voltage (VCES) with adequate margin for 480V three-phase applications
• 40A continuous collector current (IC) with third-generation IGBT chip technology for reduced VCEsat and lower conduction losses
• Integrated fast recovery anti-parallel freewheeling diodes optimized for low reverse recovery charge (Qrr)
• Standard module package with isolated copper baseplate for direct heatsink mounting and simplified thermal management
• Optimized switching characteristics reducing EMI and gate drive complexity in high-frequency inverter topologies
• Suitable for PWM switching frequencies typical of industrial VFD and servo amplifier designs

With a current factory lead time of 99 weeks direct from Infineon, procurement teams relying on standard distribution channels face serious exposure to production line stoppages and missed delivery commitments. The FP40R12KE3G is also an aging platform part, meaning allocations can tighten without warning as manufacturers prioritize newer generations. Whether you're managing an emergency breakdown, building safety stock, or replacing a legacy design in the field, waiting nearly two years for factory production is not a viable option for most operations. ATI maintains independent inventory specifically to bridge these gaps.
