DESIGN NOTE: USE OF THERMAL RESPONSE DATA
A train of periodical power pulses can be represented by
the model as shown in Figure 40. Using the model and the de-
vice thermal response the normalized effective transient ther-
mal resistance of Figure 39 was calculated for various duty
cycles.
To find ZθJA(t), multiply the value obtained from Figure 39
by the steady state value RθJA.
Example:
The MPS6523 is dissipating 2.0 watts peak under the follow-
ing conditions:
t1 = 1.0 ms, t2 = 5.0 ms. (D = 0.2)
Using Figure 39 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 RθJA = 0.22 x 2.0 x 200 = 88°C.

Note AN569/D, available from the Literature Distribution
Center or on our website at www.onsemi.com.
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 42 is based upon TJ(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 39. 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.
