Typical Collector Leakage Current A train of periodical power pulses can be represented by the model as shown in Figure 18. Using the model and the device thermal response the normalized effective transient thermal resistance of Figure 17 was calculated for various duty cycles. To find ZJA(t), multiply the value obtained from Figure 17 by the steady state value RJA. Example: Dissipating 2.0 watts peak under the following conditions: t1 = 1.0 ms, t2 = 5.0 ms (D = 0.2) Using Figure 17 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 RJA = 0.22 x 2.0 x 200 = 88°C.
