The value of anode current required to maintain the conduction of an SCR even though the gate signal is removed is called _____.

  • The value of anode current required to maintain the conduction of an SCR even though the gate signal is removed is called Latching current.
  • The latching current is defined as the minimum anode current that must be maintained through the SCR to keep it in the conducting state even when the gate signal is removed.
  • When a gate signal is applied to an SCR, it triggers the device into the conducting state, allowing a relatively small gate current to control a larger anode current.
  • Once the SCR is triggered into conduction, it will continue to conduct even if the gate signal is removed, provided that the anode current is greater than or equal to the latching current.
