DESIGN NOTE: USE OF THERMAL RESPONSE DATA
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 JA(t), multiply the value obtained from Figure 19 by the steady state value RJA. 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. The peak rise in junction temperature is therefore T = r(t) x P(pk) x RJA = 0.22 x 2.0 x 200 = 88C. For more information, see AN-569.

The safe operating area curves indicate IC-VCE 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) = 150C; TC or TA is variable depending upon conditions. Pulse curves are valid for duty cycles to 10% provided TJ(pk) 150C. 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.

The safe operating area curves indicate IC-VCE 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 18 is based upon T J(pk) = 150C; TC or TA is variable depending upon conditions. Pulse curves are valid for duty cycles to 10% provided TJ(pk) 150C. TJ(pk) may be calculated from the data in Figure 17. At high case or ambient temperatures, thermal limitations will reduce the power than can be handled to values less than the limitations imposed by second breakdown.

DESIGN NOTE: USE OF THERMAL RESPONSE DATA
A train of periodical power pulses can be represented by the model as shown in Figure 19. 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 Z JA(t), multiply the value obtained from Figure 17 by the steady state value RJA. Example: The MPS3905 is 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 = 88C. For more information, see AN-569.
