There are two limitations on the power handling ability of a
transistor: average junction temperature and second
breakdown safe operating area curves indicate I
limits of the transistor that must be observed for reliable
operation i.e., the transistor must not be subjected to
greater dissipation than the curves indicate.
The data of Figure - 6 curve is based on T
T
breakdown pulse limits are valid for duty cycles to 10%
provided T
thermal limitation will reduce the power that can be
handled to values less than the limitations imposed by
second breakdown.
C
is variable depending on power level. Second
