Disc Thyristors

Disc thyristors (press-pack SCR) are clamped between double-sided heat sinks for superior thermal performance and uniform current distribution — designed for high-power, high-current industrial applications requiring maximum reliability.

Main series: KP (phase control thyristors), KK (fast thyristors), KS, and standard thyristors. Fast thyristors, high-frequency thyristors, and bidirectional thyristors available. Voltage range 200V–8500V, current range 200A–5000A.

Key Features

  • Press-pack flat disc structure — double-sided heat sink clamping
  • Superior thermal performance — uniform current distribution
  • KP series — phase control thyristors
  • KK series — fast thyristors
  • KS series and standard thyristors available
  • Fast, high-frequency, and bidirectional thyristor options
  • Voltage range — 200V to 8500V
  • Current range — 200A to 5000A
  • Series and parallel configurations supported
  • OEM and custom specifications available

Applications

Suitable for high-power rectifier systems, medium voltage soft starters, HVDC transmission, large motor drives, industrial furnaces, induction heating, and heavy industry applications including mining and metallurgy.
