{"product_id":"410403-78aw-ir","title":"410403-78AW-IR","description":"\u003cp\u003eThe 410403-78AW-IR is an International Rectifier IGBT module rated at 78A, engineered for high-efficiency switching in industrial power electronics systems. IGBT modules in this class are widely deployed in variable frequency drives, inverters, and servo amplifiers where precise gate-controlled switching and thermal robustness are critical. IR's module architecture integrates the IGBT die and freewheeling diode in a single isolated package, reducing system complexity and improving thermal management at elevated current levels typical of continuous industrial duty cycles.\u003c\/p\u003e\u003cp\u003eThis module is well suited for applications including AC motor drives, UPS systems, induction heating equipment, welding inverters, and renewable energy converters such as solar inverters and wind turbine controllers. Maintenance engineers specifying replacement parts for legacy drive platforms frequently encounter the 410403-78AW-IR in established OEM designs. Its 78A current rating makes it a practical fit for medium-power three-phase drive topologies and single-phase bridge configurations found throughout manufacturing, material handling, and process control environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick Reference: 410403-78AW-IR\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e410403-78AW-IR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eInternational Rectifier (IR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eIGBT Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Rating\u003c\/td\u003e\n\u003ctd\u003e78A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003eContact ATI to Confirm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAvailability\u003c\/td\u003e\n\u003ctd\u003eIn Stock — Same-Day Shipping\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eKey Features of the 410403-78AW-IR:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e78A continuous collector current rating suitable for medium-power industrial drive topologies\u003c\/li\u003e\n\u003cli\u003eInternational Rectifier IGBT technology providing low saturation voltage (Vₙₜₛ(sat)) for reduced conduction losses\u003c\/li\u003e\n\u003cli\u003eIntegrated co-pack freewheeling diode for commutation clamping without external rectifier components\u003c\/li\u003e\n\u003cli\u003eElectrically isolated baseplate for direct heatsink mounting in standard power module assemblies\u003c\/li\u003e\n\u003cli\u003eOptimized switching characteristics supporting PWM operation in variable frequency drive and inverter applications\u003c\/li\u003e\n\u003cli\u003eRobust wire-bond and die-attach construction rated for extended thermal cycling in continuous-duty environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInternational Rectifier IGBT modules of this series are no longer in active production, making the 410403-78AW-IR a long-lead-time and increasingly scarce component in the open market. Procurement teams supporting legacy drive platforms often face extended downtime when sourcing discontinued IR modules through standard distribution channels.
