3 Phase Control Thyristor


We provide one of the most comprehensive ranges of standard phase control thyristors in the industry. Devices with voltage ranges from 600V to 6500V are available, these devices are optimized to give low conduction losses and are primarily intended for applications with line frequencies up to 400Hz.

Features:


  • Distributed Amplifying Gate Design
  • Low Turn on losses
  • 24V dual output for FAN
  • Reduced Reverse Recovery charges
  • Low Turn of time
  • Narrow Vt band (All thyristors simultaneously switches on and off).

Applications:
  • industrial DC drives
  • induction melting
  • marine/rail propulsion systems
  • wind power converters
  • electrochemical power supplies
  • soft starters

4 Fast Turn-off Thyristors


Fast switching thyristors have regenerative gate structure to ensure low switching losses and high di/dt performance in additional to pressure contact technology these devices offer lower reverse recovery charge values, low forward switching losses and high reliability.

Features:


  • Distributed Amplifying Gate Design
