Complete the following steps to enter Junction Capacitances data:

  1. Click the Junction capacitance chart tab.
  2. In the databook, find the “Typical Junction Capacitance” chart—for example:

  3. Find the junction capacitance at zero reverse voltage and enter it in the Junction capacitance at zero reverse voltage (CJO) field.

    If this information is not given in the databook, select Check if data not available.

  4. Find the point of lowest reverse voltage, or the beginning point of the curve. Use the coordinates of this point to enter the values for:
    • Junction capacitance (CJ1)
    • Lowest reverse voltage (Vr1)
  5. Find the point of highest reverse voltage, or the end point on the curve) and enter the coordinate values in the Junction capacitance (CJ4) and Highest reverse voltage (Vr4) fields.
  6. Select two additional intermediate points on the graph, greater than the lowest reverse voltage but in the lower range of the reverse voltage.
  7. Use the coordinate values of the second point to enter:
    • Junction capacitance (CJ2)
    • Second to lowest reverse voltage (Vr2)
  8. Use the coordinate values of the third point to enter:
    • Junction capacitance (CJ3)
    • Second to highest reverse voltage (Vr3)
