The FP35R12KT4_B11ENG is a 1200V, 35A IGBT module from EUPEC, a brand recognized for precision-engineered power semiconductor solutions used in demanding industrial environments. Built for high-frequency switching with low conduction losses, this module integrates IGBT chips with fast recovery freewheeling diodes in a compact, isolated package. Its construction is optimized for reliability under thermal cycling and high-repetition switching loads, making it a proven choice for engineers specifying components in motor drives, inverters, and industrial UPS systems.

The FP35R12KT4_B11ENG is well-suited for a wide range of industrial power electronics applications including variable frequency drives (VFDs), servo amplifiers, solar inverters, induction heating equipment, and regenerative braking systems. Its 1200V blocking voltage provides adequate margin for 690V AC bus applications, while the 35A current rating targets mid-power converter stages where switching efficiency and thermal management are primary design concerns. The module's isolated baseplate simplifies heatsink integration and supports standard mounting configurations common in OEM and retrofit designs.

Key Features of the FP35R12KT4_B11ENG:

• 1200V collector-emitter voltage (VCES) with 35A continuous collector current rating for mid-power industrial converter stages
• Integrated fast recovery freewheeling diodes co-packaged with IGBT chips for reduced external component count and improved switching performance
• Low VCE(sat) characteristics minimize conduction losses and reduce heatsink thermal requirements in continuous-duty applications
• Electrically isolated copper baseplate enables direct heatsink mounting without additional insulation hardware, simplifying mechanical integration
• Optimized gate charge and switching times support operation at elevated carrier frequencies in VFD and inverter topologies
• EUPEC's proven IGBT chip technology delivers high ruggedness under short-circuit and overcurrent transient conditions common in industrial environments

The FP35R12KT4_B11ENG carries a factory lead time of 99 weeks for new production — a timeline that can halt equipment repairs, delay production line restarts, and strand OEM build schedules. EUPEC modules in this class are increasingly difficult to source through standard distribution channels as legacy platforms age out of active production. Procurement teams managing MRO inventory, spares pools, or active production builds cannot afford to rely solely on factory order pipelines. Securing verified stock from a specialized distributor is the only reliable path to short-cycle delivery on parts like this.
