Gate turn-off thyristors (GTO)
The production of Gate turn-off thyristors started from 1980s.GTOs are improved for low conduction losses. GTOs are, by nature, relatively slow switches.
All ABB GTOs are press-pack devices. They are pressed with a relatively high force onto heat-sinks which also serve as electrical contacts to the power terminals.
You can choose the right one for your application from our broad range of thyristors of ABB. A&S is the supplier you can count on.
