  • Semikron SCR/Diode Thyristor Module — 57A, 2000V
  • Description

    The SKKH57/20EH4 from Semikron is a high-voltage SCR/diode combination module delivering 57 amperes of current capability and a 2000V voltage rating. This thyristor-diode module is engineered for controlled rectification, featuring a silicon-controlled rectifier (SCR) paired with a freewheeling diode in a single, thermally efficient package. Its robust construction and Semikron's proven SKKH-series platform make it a trusted solution for industrial power conversion systems where reliability and high blocking voltage are critical.

    The SKKH57/20EH4 is widely used in AC/DC converters, motor drive front-ends, soft starters, uninterruptible power supplies (UPS), battery chargers, and DC power supplies. Its integrated diode simplifies circuit design, reduces component count, and minimizes board space while maintaining the thermal performance required for continuous industrial operation. The module is suitable for three-phase half-controlled bridge rectifier topologies and other demanding power electronic configurations.
