SCR Thyristor TO-3 Package

Thyristors (SCR’s) are constructed with glass passivated chips and are assembled in high reliable, robust hermetic sealed housing structures. They are mechanically strong and are stable under negative environmental conditions.

These devices have high reliability and exceptional stability at high temperatures.They have superior surge capabilities and feature low thermal resistance.

SCR’s are used in applications where high currents and voltages are involved. AC switches, bridge rectifier converters, DC motor controls, welding, AC motor drives, soft starters, etc.

  • The current range starts from 25A upto 170A, with voltages upto 1600V.
  • Devices are available in Stud Base packages, with Metric and UNF Threads.
