Figure 2. Thermal Response — 2N3771, 2N3772
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.
Figure 3 is based on JEDEC registered Data. Second
breakdown pulse limits are valid for duty cycles to 10%
provided TJ(pk) < 200_C. TJ(pk) may be calculated from the
data of Figure 2. Using data of Figure 2 and the pulse power
limits of Figure 3, TJ(pk) will be found to be less than TJ(max)
for pulse widths of 1 ms and less. When using ON
Semiconductor transistors, it is permissible to increase the
pulse power limits until limited by TJ(max).
