DESIGN NOTE: USE OF THERMAL RESPONSE DATA
A train of periodical power pulses can be
represented by the model as shown in Figure 20. 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 R
JA
.
Example:
The MPS6521 is dissipating 2.0 watts peak under the
following conditions:
t
1
= 1.0 ms, t
2
= 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 R
JA
= 0.22 x 2.0 x 200 = 88
°
C.

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 22 is based upon T

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.
