The IRKT250-16N is a 250A, 1600V IGBT module manufactured by International Rectifier, built for high-power switching applications where reliability and voltage blocking capability are non-negotiable. This module integrates an insulated gate bipolar transistor with a fast-recovery antiparallel freewheeling diode, making it a drop-in solution for half-bridge, chopper, and inverter leg configurations. Its robust construction and thermal performance make it a proven choice for engineers designing or maintaining equipment that operates under sustained high-current and high-voltage conditions in industrial and transportation environments.

The IRKT250-16N sees widespread use across industrial AC and DC motor drives, regenerative braking systems, traction inverters, UPS systems, induction heating equipment, and medium-voltage power supplies. Its 1600V blocking voltage provides adequate headroom for applications powered from three-phase mains with transient overvoltage exposure. Maintenance engineers servicing older variable frequency drives, crane controls, elevator drives, and rail auxiliary converters frequently specify this module as a direct replacement when original equipment IGBTs fail or degrade under thermal cycling stress.

Key Features of the IRKT250-16N:

• 1600V collector-emitter voltage (VCES) with 250A continuous collector current rating for high-power density switching
• Integrated fast-recovery antiparallel freewheeling diode eliminates the need for external flyback diodes in bridge topologies
• Low VCE(sat) minimizes conduction losses during on-state operation, improving overall system efficiency at full load
• Isolated baseplate construction provides electrical isolation between the power circuit and heatsink, simplifying thermal management design
• Optimized for hard-switched PWM inverter duty with gate drive compatibility for standard IGBT driver ICs
• Package form factor and pin-out consistent with International Rectifier's IRKT series, ensuring direct drop-in replacement capability

With a published factory lead time of 99 weeks for new production, procurement teams relying solely on the original manufacturer pipeline face serious exposure to equipment downtime and project delays. The IRKT250-16N is an established part used in long-service-life industrial equipment, and sourcing challenges are common. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time IGBT modules specifically to support maintenance operations and OEM production lines that cannot absorb multi-year procurement delays. Having a stocking distributor with verified OEM product on hand is the difference between a scheduled repair and an extended outage.

ATI Accurate Technology is located in Palmetto, Florida and specializes in IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long-lead-time parts.
