(d = 0.2) using f igure 19 at a pulse width of 1.0 ms and d = 0.2, the reading of r(t) is 0.22. the peak rise in junction temperature is therefore t = r(t) x p (pk) x r ja = 0.22 x 2.0 x 200 = 88 c. for more information, see an ? 569. the safe operating area curves indicate i c ? v ce limits of the transistor that must be observed for reliable operation. collector load lines for specific circuits must fall below the limits indicated by the applicable curve. the data of figure 20 is based upon t j(pk) = 150 c; t c or t a is variable depending upon conditions. pulse curves are valid for duty cycles to 10% provided t j(pk) 150 c. t j(pk) may be calculated from the data in figure 19. at high case or ambient temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. 10 -2 10 -1 10 0 10 1 10 2 10 3 -2 0 0 + 20 + 40 + 60 + 80 + 100 + 120 + 140 + 160 v cc = 30 vdc i ceo i cbo and i cex @ v be(off) = 3.0 vdc t a = 25 c current limit thermal limit second breakdown limit 1.0 ms 10 s t c = 25 c 1.0 s dc dc 4.0 6.0 10 20 40 60 100 200 4.0 6.0 8.0 10 20 40 t j = 150 c 100 s
