The thermal coefficient of V F(BR) is similar to that of a zener
diode. I BO falls with temperature, reducing the zener
impedance contribution to V BO . This causes the V BO
temperature coefficient perature to be less than or equal to the
V F(BR) coefficient. The graph allows the estimation of the
maximum voltage rise of either parameter.

Note: The behavior of the breakover current during AC operation
is complex, due to junction heating, case heating and thermal
interaction between the device halves. Microplasma conduction
at the beginning of breakdown sometimes results in higher local
current densities and earlier than predicted switching. This
reduces power dissipation and stress on the device.
