Diode Thyristor & SCR Modules
silicon controlled rectifier (SCR) and thyristor modules include four main series: 5STP (plate-type phase-controlled thyristor), 5SDD (diode/thyristor hybrid module), 5SHX/5SHY (IGCT integrated gate-commutated thyristor), and SKKT/SSKT (press-fit module). These components are engineered for demanding applications across industrial drives, high-voltage frequency conversion, wind power, power grids, and rail transportation systems.
