The IRKT41-14S90 is an International Rectifier (IR) IGBT module rated at 41 amperes and 1400 volts, engineered for high-voltage power switching applications where reliability and thermal stability are critical. This module integrates an IGBT with an antiparallel diode in a rugged industry-standard package, offering low saturation voltage and fast switching characteristics. It is well-suited for designs requiring elevated DC bus voltages, making it a dependable solution in variable-speed drives, inverters, and industrial power conversion systems operating near or above 1000V DC bus levels.

The IRKT41-14S90 sees widespread use across demanding industrial sectors including AC and DC motor drives, regenerative braking systems, UPS and standby power infrastructure, induction heating equipment, welding inverters, and traction control systems. Its 1400V blocking voltage rating provides the necessary headroom for designs operating on high-voltage grids or in applications with significant voltage transients. Engineers specify this module where output reliability, long service life, and consistent switching behavior under variable load conditions are non-negotiable requirements.

Key Features of the IRKT41-14S90:

• 1400V VCES blocking voltage providing robust margin for high-voltage bus designs and transient-heavy environments
• 41A continuous collector current rating suitable for mid-range industrial drive and inverter topologies
• Integrated antiparallel freewheeling diode for simplified circuit design and reduced external component count
• Low VCE(sat) characteristics minimize conduction losses and reduce thermal stress on the module and heatsink assembly
• Industry-standard power module footprint for straightforward drop-in replacement and compatibility with existing drive platforms
• Isolated baseplate construction supports direct mounting to heatsinks, simplifying thermal management in densely packaged power stages

With a factory lead time of 99 weeks for new production, the IRKT41-14S90 presents a genuine procurement challenge for maintenance teams managing critical equipment uptime and for OEMs building against scheduled production runs. When a drive or inverter system goes down unexpectedly, waiting nearly two years for factory-fresh stock is not an option. ATI Accurate Technology maintains inventory of hard-to-find, long-lead-time, and discontinued IR IGBT modules precisely for these situations, providing engineers and procurement professionals with a dependable source when the supply chain cannot respond in time.

ATI Accurate Technology is located in Palmetto, Florida and specializes in power semiconductors including IGBTs, thyristors, diodes, and rectifier modules.
