The 701819-303AC-IR is a 303A IGBT module from International Rectifier, engineered for high-power switching applications where reliability and thermal performance are critical. As a well-established IR platform, this module delivers the low saturation voltage, fast switching characteristics, and robust short-circuit ruggedness that design engineers and field maintenance teams depend on in continuous-duty industrial environments. Its form factor and terminal configuration are optimized for direct integration into existing drive and converter architectures, minimizing redesign time when sourcing a replacement.

This IGBT module is widely used in AC motor drives, regenerative drive systems, UPS inverters, induction heating equipment, and industrial servo amplifiers. The 303A current rating makes it well-suited for medium-to-high horsepower drive stages found in steel processing, paper mills, pump and fan control, and heavy manufacturing automation. OEMs and MRO teams maintaining legacy IR-based drive platforms will recognize this part number as a direct-fit solution for keeping critical equipment operational without costly system overhauls.

Key Features of the 701819-303AC-IR:

• 303A continuous collector current rating suitable for high-power industrial drive stages
• International Rectifier IGBT technology with low V_CE(sat) for reduced conduction losses
• Fast switching performance supports high switching frequency operation with controlled dV/dt
• Integrated gate structure with short-circuit withstand capability for enhanced fault tolerance
• Robust base plate and module housing designed for direct heatsink mounting with reliable thermal interface
• Drop-in replacement compatibility with legacy IR drive platforms, reducing retrofit engineering time

With a current factory lead time of 99 weeks for new production, the 701819-303AC-IR presents a serious procurement challenge for facilities that cannot afford extended downtime or schedule delays. Infeon's acquisition of International Rectifier has further complicated direct factory sourcing for legacy IR module part numbers. For MRO buyers, plant engineers, and OEM service departments managing aging drive inventories, securing stock through an experienced distributor is the only practical path to near-term availability. ATI maintains inventory of hard-to-find and long-lead-time IGBT modules precisely to bridge this supply gap.
