DESCRIPTION
The 55PT series of silicon controlled rectifiers are
high performance glass passivated technology,
and are suitable for general purpose applications,
where power handling and power dissipation are
critical, such as solid state relay, welding equipment
and high power motor control.

Base on a clip assembly technology, they offer a
superior performance in surge current capabilities.
Thanks to their internal ceramic pad, they provide
high voltage insulation(2500VRMS).
