Additional Details

The SKKH172/16E thyristor module is designed for phase control applications where precise control of AC power is required. The '172' in the part number refers to the average on-state current rating (172 Amperes), and the '16' refers to the blocking voltage rating (1600 Volts). The 'E' suffix indicates a specific package or feature variation. The electrically isolated base plate simplifies mounting and heatsinking. The module uses pressure contact technology, which provides reliable electrical and thermal contact between the thyristor chips and the base plate. This technology enhances the module's ability to withstand thermal cycling and mechanical stress. Proper heatsinking is crucial for the reliable operation of the thyristor module. The amount of heatsinking required depends on the operating conditions, such as the average current and ambient temperature. The module's high surge current capability allows it to withstand temporary overloads without damage. The gate trigger current required to turn on the thyristor is typically low, making it easy to interface with control circuitry.
