DG646BH

The DG646BH GTO thyristor from Dynex is a high-power bipolar semiconductor switch that combines high voltage blocking with active gate turn-off capability. GTO devices can be actively switched off by a negative gate pulse, unlike standard SCRs which turn off only when current falls below holding levels. This capability enables more compact and efficient high-power inverters, converters, motor drives, and chopper circuits. Its robust construction and double-side cooling ensure stability under heavy industrial duty cycles.
