There are two limitations on the power handling ability of a

transistor: average junction temperature and second break-

down. Safe operating area curves indicate IC – VCE opera-

tion i.e., the transistor must not be subjected to greater

dissipation than the curves indicate.

The data of Figure 5 is based on TJ(pk) = 150

C; TC

is variable depending on conditions. Second breakdown

pulse limits are valid for duty cycles to 10% provided TJ(pk)

150

C. At high case temperatures, thermal limitations will

reduce the power that can be handled to values less than the

limitations imposed by second breakdown.
