• Description

  Т643-320 is a phase control thyristor in disc design. It has a repetitive peak off-state and reverse voltage VDRM/VRRM 4600-6500 V. Mean on-state current ITAV 320 А. The thyristor has an industry-standard ceramic housing making it easy to integrate the device into existing equipment. The maximal junction temperature Tjmax is 125 °C.
  
  Phase control thyristors are widely used to control high load with a low control signal applied to the control gate. They can be used in electrical systems for various industries, including AC and DC circuits operating at industry standard or increased frequency. The thyristors have a sealed housing isolating the functional part and the semiconductor element from mechanical impacts and environment.
  
  This thyristor has a disc housing with pressure contacts. Disc thyristors are notable for the possibility of two-sided cooling.
  
  Thyristors from Proton-Electrotex have the following features:

  ∙ low static and dynamic losses;
  ∙ high values of VDRM/VRRM;
  ∙ extensive experience of using the devices in various industries;
  ∙ range of voltages from 100 to 6500 V and amperages from 125 to 5000 A;
  ∙ high resistance to thermal and electric cycling;
  ∙ natural or forced air cooling.
  
  Proton-Electrotex is able to select the optimal power thyristor for given operation modes at the customer's request. It is also possible to ship ready-to-use power semiconductors in assembly with heatsinks.
