The Infineon FP50R12KT4 is a 1200V, 50A IGBT module built on Infineon's proven TRENCHSTOP™ 4 chip technology, delivering a strong balance of low switching losses and robust short-circuit withstand capability. The module integrates an inverse diode and is housed in a compact EconoPACK™ footprint, making it well-suited for space-constrained designs where thermal performance and reliability are non-negotiable. With its optimized gate charge and tight parameter distribution, the FP50R12KT4 simplifies paralleling and gate drive design for experienced power electronics engineers.

The FP50R12KT4 serves a broad range of demanding industrial and commercial applications, including variable-speed motor drives, solar and wind energy inverters, three-phase UPS systems, induction heating equipment, and welding power supplies. Its 1200V blocking voltage and 50A continuous collector current rating make it a reliable choice for medium-power converter stages operating from standard three-phase line voltages. The module's well-characterized switching behavior also makes it attractive for designers replacing legacy components in existing platforms or upgrading aging drive systems.

Key Features of the FP50R12KT4:

• 1200V VCES and 50A IC rating suitable for medium-power three-phase inverter topologies
• TRENCHSTOP™ 4 IGBT technology providing reduced saturation voltage (VCEsat) and low switching losses across the operating range
• Integrated inverse freewheeling diode with soft recovery characteristics to minimize EMI and voltage overshoot
• EconoPACK™ module package with isolated baseplate for simplified heatsink mounting and thermal management
• Short-circuit withstand time (tsc) of 10µs for enhanced fault tolerance in drive and inverter designs
• Tight IC and VCEsat distribution enabling reliable paralleling without additional derating

With a current factory lead time of 99 weeks on new production, the FP50R12KT4 presents a serious procurement challenge for maintenance teams managing unplanned downtime and for OEMs managing production schedules. Extended lead times on Infineon IGBT modules have become increasingly common across the power semiconductor supply chain. Having a stocking distributor with immediate inventory is often the only practical path to keeping critical equipment operational or maintaining a production line without costly delays. ATI Accurate Technology maintains ready stock of hard-to-find and long-lead-time IGBT modules precisely for situations like this.
