The FP50R12KT4_B16 is an Infineon EconoPACK+ series IGBT module rated for 50A collector current and 1200V blocking voltage. Utilizing Infineon's fourth-generation TRENCHSTOP IGBT4 and emitter-controlled diode technology, this module delivers reduced conduction and switching losses compared to previous generations. The B16 designation indicates the enhanced isolation voltage variant, featuring a 4.0kV AC isolation-rated DCB substrate. Its compact EconoPACK+ housing simplifies thermal management with a flat baseplate optimized for direct heatsink mounting, making it a reliable choice for demanding power electronic designs.

The FP50R12KT4_B16 is well-suited for a broad range of industrial power conversion systems. Typical applications include AC motor drives, servo amplifiers, uninterruptible power supplies (UPS), solar inverters, and industrial welding equipment. The module's low V_CE(sat) and optimized anti-parallel diodes support high switching frequencies required in modern PWM-controlled inverters and converters. Its rugged construction and defined short-circuit withstand capability make it appropriate for harsh industrial environments where reliability and uptime are critical operational requirements.

Key Features of the FP50R12KT4_B16:

• TRENCHSTOP IGBT4 chip technology with low V_CE(sat) for reduced conduction losses at rated current
• Integrated emitter-controlled anti-parallel freewheeling diodes with optimized reverse recovery characteristics
• Enhanced isolation voltage: 4.0kV AC (B16 variant) for compliance with stringent safety requirements
• EconoPACK+ package with flat copper baseplate for efficient and uniform heat transfer to heatsink
• Defined short-circuit withstand time (t_SC) supporting robust overcurrent protection in drive applications
• Compatible with standard EconoPACK+ gate driver and mechanical footprint for drop-in replacement scenarios

Infineon's current factory lead time for the FP50R12KT4_B16 stands at 99 weeks — nearly two years — making open-market procurement critical for any project, repair, or production line that cannot afford that delay. Obsolescence risk and supply chain disruptions continue to pressure maintenance and procurement teams across industrial sectors. Whether you need a single replacement module for an urgent field repair or a larger quantity to buffer inventory, sourcing from a stocking distributor is the most effective way to keep operations running without costly downtime waiting on factory allocation.
