SKM400GB12F4
The SKM400GB12F4 is a high-performance IGBT (Insulated Gate Bipolar Transistor) module from Semikron's SEMITRANS 3 series, designed to meet the rigorous demands of industrial and commercial power electronics applications. With a nominal collector current of 400 A and a maximum collector-emitter voltage of 1200 V, this module delivers exceptional performance and reliability. Its advanced CAL4 ultra-fast soft-switching technology ensures efficient operation, making it ideal for systems requiring high switching frequencies above 15 kHz.
Built for durability and efficiency, the SKM400GB12F4 features a high-speed trench and field-stop IGBT design, coupled with a CAL4 ultra-fast soft-switching diode. The module's insulated copper baseplate, utilizing Direct Bonded Copper (DBC) technology, enhances thermal management and power cycling capabilities. These features contribute to the module's robustness, allowing it to operate effectively in demanding environments. Its compact dimensions (106 x 62 x 31 mm) and SEMITRANS 3 housing facilitate easy integration into various power electronic systems.
Ideal for a range of applications, the SKM400GB12F4 is commonly used in uninterruptible power supplies (UPS), electronic welders, inductive heating systems, and switched-mode power supplies. Its ability to handle high currents and voltages, combined with efficient thermal performance, makes it a reliable choice for industrial and commercial power electronics.
