VOLTAGE AND CURRENT WAVEFORMS
NOTE A: Input pulse width is increased until ICM = 0.63A.
NOTE B: Sidac (or Diac or series of Diacs) chosen so that VBO is just below VCEO rating of transistor to be protected.
The Sidac (or Diac) eliminates a reverse breakdown of the transistor in inductive switching circuits where otherwise the
transistor could be destroyed.
