{"product_id":"fs300r12ke3_s1-infineon","title":"FS300R12KE3_S1-INFINEON","description":"\u003cp\u003eThe Infineon FS300R12KE3-S1 is a high-power IGBT module in the IGBT4 family, delivering 300A continuous collector current at a 1200V blocking voltage. Built on Infineon's fourth-generation Trench\/Fieldstop IGBT chip technology paired with soft-recovery emitter-controlled diodes, this module offers low conduction losses, controlled switching behavior, and excellent short-circuit ruggedness. The -S1 configuration variant is engineered for demanding converter topologies where thermal performance and switching reliability under continuous heavy load are non-negotiable design requirements.\u003c\/p\u003e\u003cp\u003eThe FS300R12KE3-S1 is widely deployed in industrial AC motor drives, regenerative inverters, medium-voltage UPS systems, induction heating equipment, and traction auxiliary converters. Its switching characteristics make it well suited for three-phase inverter bridge legs operating at switching frequencies typically between 1 and 4 kHz. Industries including steel, paper, oil and gas, marine propulsion, and renewable energy infrastructure rely on this module for drivetrain control and power conversion stages where uptime directly impacts production output and operational safety.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick Reference: FS300R12KE3-S1\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eFS300R12KE3-S1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eInfineon Technologies\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\u003eContinuous Collector Current (IC)\u003c\/td\u003e\n\u003ctd\u003e300A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCollector-Emitter Voltage (VCES)\u003c\/td\u003e\n\u003ctd\u003e1200V\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 FS300R12KE3-S1:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1200V VCES blocking voltage with 300A rated continuous collector current, suitable for high-power three-phase inverter bridge configurations\u003c\/li\u003e\n\u003cli\u003eInfineon 4th-generation Trench\/Fieldstop IGBT technology delivering reduced VCEsat for lower conduction losses at rated current\u003c\/li\u003e\n\u003cli\u003eIntegrated soft-recovery emitter-controlled freewheeling diodes minimize reverse-recovery stress and radiated EMI in hard-switching topologies\u003c\/li\u003e\n\u003cli\u003eIndustry-standard 62mm housing footprint with isolated baseplate enables direct drop-in replacement across a wide range of existing drive platforms\u003c\/li\u003e\n\u003cli\u003eShort-circuit withstand capability rated at 10µs provides protection margin in overcurrent fault events common in industrial drive environments\u003c\/li\u003e\n\u003cli\u003eLow thermal resistance junction-to-case (RthJC) supports efficient heat extraction into liquid-cooled or forced-air heatsink assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWith Infineon's current factory lead time for the FS300R12KE3-S1 sitting at 99 weeks, procurement teams sourcing for maintenance spares, emergency replacements, or new build schedules face significant exposure. Supply chain disruptions, end-of-life production shifts, and allocation constraints across major distributors have made spot availability of this module increasingly difficult to secure. For maintenance engineers managing critical drive systems, waiting nearly two years for a factory order is simply not viable. Having a reliable stocking distributor with verified new OEM inventory is the only practical solution for keeping systems operational and capital projects on schedule.\u003c\/p\u003e\u003cp\u003eATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including hard-to-find and long-lead-time parts like the FS300R12KE3-S1.
