Holding current
|
Latching current
|
Holding current is associated with turn-off process of SCR
|
Latching current is associated with turn-on process of SCR
|
Thyristor can be turned-off or returned to forward blocking state only if the forward current falls below a low level current called the holding current.
|
It is the minimum value of anode current Which it must attain during turn-on process to maintain conduction when gate pulse is removed.
|
Holding current is less than the latching current.
|
Latching current is the 2 to 3 times of holding current.
