Thermal Response 104 DESIGN NOTE: USE OF THERMAL RESPONSE DATA IC, COLLECTOR CURRENT (nA) VCC = 30 Vdc A train of periodical power pulses can be represented by the model as shown in Figure 19A. Using the model and the device thermal response the normalized effective transient thermal resistance of Figure 19 was calculated for various duty cycles. To find Z θJA(t), multiply the value obtained from Figure 19 by the steady state value RθJA. Example: The MPS3904 is dissipating 2.0 watts peak under the following conditions: t1 = 1.0 ms, t2 = 5.0 ms. (D = 0.2) Using Figure 19 at a pulse width of 1.0 ms and D = 0.2, the reading of r(t) is 0.22. 103 102 ICEO 101 ICBO AND ICEX @ VBE(off) = 3.0 Vdc 100 10–1 10–2 –4 0 –2 0 0 + 20 + 40 + 60 + 80 + 100 + 120 + 140 + 160 TJ, JUNCTION TEMPERATURE (°C) The peak rise in junction temperature is therefore ∆T = r(t) x P(pk) x RθJA = 0.22 x 2.0 x 200 = 88°C.

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; TC or TA is variable depending upon conditions. Pulse curves are valid for duty cycles to 10% provided TJ(pk) ≤ 150°C. TJ(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.
