Additional Details

The SKKH72/18E is a phase control thyristor module where '72' represents the average on-state current (72A) and '18' representing the blocking voltage (1800V). The isolated base plate simplifies heatsink mounting, reducing assembly time and cost. The module is designed to withstand high surge currents, enhancing its robustness in demanding applications. Pressure contact technology ensures reliable thermal and electrical contact between the thyristor die and the base plate. This design enables excellent heat dissipation and contributes to the module's overall reliability. The low on-state voltage drop minimizes power losses, improving the efficiency of the power conversion system. Proper heatsinking is critical to ensure the thyristor operates within its safe operating area. The required heatsink size depends on the operating current and ambient temperature. The gate triggering characteristics are designed for easy interfacing with control circuitry, allowing for precise and efficient control of the thyristor.
