Protection Thyristors

The silicon based thyristors of the manufacturer ProTek Devices are crowbar devices.
Due to their characteristic they are able to handle high surge currents at higher trigger voltages.
Through its bidirectional design these thyristors switch AC voltages.
Once the voltage exceeds a certain threshold voltage, it turns on and becomes conductive.
They are switched-off by falling below the holding current.

Features

  • bidirectional crowbar transient voltage protection
  • Size: SMB (DO-214AA)
  • breakdown voltages from 77 to 400V
  • typical capacitance of 30 - 120pF
  • ESD protection < 40kV
  • suitable for telecommunication and RF-applications
