  • Description

    The SKKT570/18E is a high-power dual thyristor (SCR) module manufactured by SEMIKRON, rated for 570 amperes of average on-state current and a repetitive peak off-state voltage of 1800V. Built on SEMIKRON's proven SKKT platform, this module integrates two thyristors in a common cathode or inverse parallel configuration within a robust, isolated base package, making it ideal for high-voltage, high-current industrial power electronics applications requiring reliable and efficient phase control.

    The SKKT570/18E is widely deployed across a broad range of industrial applications including AC motor soft starters, DC motor drives, industrial heating and temperature control systems, battery chargers, uninterruptible power supplies (UPS), welding equipment, and three-phase rectifier bridge assemblies. Its substantial current and voltage ratings make it particularly well suited for heavy industrial environments where thermal performance, reliability, and long service life are critical requirements.
