In the field of industrial power electronics, few components are as critical—and as heavily relied upon—as the phase control thyristor disc. Among global suppliers, Russian-manufactured phase control thyristor discs stand out for their robust design, wide availability, and reliable performance in high-power environments.

These devices are essential in applications that demand precise current control, high surge resistance, and extended thermal endurance. Whether installed in rectifiers, DC drives, or soft starters, Russian thyristor discs remain a dependable solution for system integrators worldwide.

What Is a Phase Control Thyristor Disc?

A phase control thyristor is a type of semiconductor device used to manage AC power by controlling the phase angle of the voltage waveform. The disc type package refers to its press-pack construction, which offers superior heat dissipation, compact mechanical form, and high surge handling capabilities.

Compared to plastic modules, disc thyristors provide:

• Low thermal resistance

• Long operational life

• High voltage blocking (typically 1200V–6500V)

• Surge current ratings up to 30kA or higher

These qualities make them ideal for harsh environments and mission-critical applications.

Why Choose Russian-Made Thyristor Discs?

Russian factories have a long-standing legacy of producing heavy-duty power semiconductors, particularly for defense, aerospace, and large-scale industrial use. Today, many of these thyristor models have gained global recognition for their performance-to-cost ratio.
