Detailed Product Overview
The EUPEC FZ1200R12KF1 is a robust high-current IGBT module intended for industrial power electronics systems requiring high continuous current capability in a single-switch topology. With a 1200 V blocking voltage and 1200 A continuous collector current rating, the module is suitable for medium- to high-power conversion stages.
The device supports a repetitive peak collector current of 2400 A for short durations (1 ms), allowing it to handle transient overloads and inrush conditions common in motor drives and inverter applications. Total power dissipation reaches 7800 W, requiring appropriate heatsinking or liquid cooling for continuous operation at rated current.
Typical applications include high-horsepower AC drives (examples in secondary sources reference Allen-Bradley 1336 systems in the 400–800 HP range), uninterruptible power supplies, and industrial inverters. The module is supplied in a standard high-power module package with screw terminals for power connections.
Note that EUPEC was acquired by Infineon Technologies; the part may appear under either brand depending on production date and distribution channel. For new designs, engineers should verify availability and consider current Infineon high-power IGBT module families as potential alternatives.
