C717
53mm / 4.5kV THYRISTOR
Type C717 thyristor is suitable for phase control applications such as HVDC valves, static VAR
compensators and synchronous motor drives.
The silicon junction is manufactured by the proven multi-diffusion process and is supplied in an
industry standard disc-type package, ready to mount to forced or naturally cooled heat dissipators
using commercially available mechanical clamping hardware.
