BONDING WIRE LIMIT
THERMALLY LIMITED @ TC = 25°C (SINGLE PULSE)
SECOND BREAKDOWN LIMIT
There are two limitations on the power handling ability of
a transistor: average junction temperature and second
breakdown. Safe operating area curves indicate IC VCE
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
2 is based on TC = 25°C; TJ(pk) is
variable depending on power level. Second breakdown
pulse limits are valid for duty cycles to 10% but must be
derated for temperature according to Figure
1.
