Holding current

The holding  current is  the value  of on state  current  required  to maintain  conduction once the  device  the device has  fully timed  on and  the  gate current  has been removed. The  on state  current  must have  previously  exceeded the  latching current  Ti. To  turn  off A thyristor  the load current  must remain   below  Iii for sufficient time to tallow a return to the off state. This condition must be met  at the  highest operating junction temperature. Therefore it is the  minimum value of  anode current below which it must fall for taming off the thyristor. It  may also  define as the minimum anode current that must  be following  to keep  the device in a regenerative on state  condition. Below this holding  current  value the device  will return  to a blocking  state of  condition.
