Diode/Thyristor Stacks Applications

The SEMISTACK CLASSIC product range is designed for fast integration of industrial rectifiers and AC controllers. Each power stack has been sized to embed semiconductors with a suitable RC commutation topology, proper AC fuses and cooling devices. The high power range has been improved using a new heatsink profile, resulting in modularity, various fan options, low maintenance and weight reductions.

Diode/Thyristor Stacks Product Range

The SEMISTACK family consists of a broad portfolio of over 200 stacks with different topologies of uncontrolled, half-controlled and fully controlled rectifiers. These products are available with natural or forced cooling, with or without fuses. All SEMISTACK Classics include RC snubber circuitry and are optimized for fast cabinet integration.
