Holding current
- It is defined as the minimum anode current beyond SCR turns off.
- The holding current is associated with turned off process.
- The holding current is always less than the latching current.
- It is given mili – ampere. The SCR is turned off if the anode current reduces below 5 milli ampere for the specific rating of holding current milli ampere in the data sheet.
Latching current
- It is defined as the minimum anode current requires keeping turned on SCR after removing gate signal.
- The latching current is associated with turned on process.
- The value of latching current is approximately 2 to 3 times to that of holding current.
- The value of holding current and latching current is constant and it does not depend on gate current magnitude.
