      To calculate the average on-state current rating (ITAV) for an SCR, using the provided values:

      We have:

      – Average current (Iavg) = I/4

      – RMS current (Irms) = I/2

      – Maximum RMS on-state current (Irms_max) = 35 A

      1. Since we have the IRMS expression:

      [

      I = 2 times Irms = 2 times (I/2) = I implies Irms = I/2 quad text{(already given)}

      ]

      2. Substitute the given ( Irms ):

      [

      I/2 = 35 A implies I = 70 A

      ]

      3. Calculate the average current:

      [

      Iavg = I/4 = 70 A / 4 = 17.5 A

      ]

      Thus, the average on-state current rating (ITAV) is 17.5 A.

      Final answer:

      ITAV = 17.5 A
