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 R
JA
.
Example:
Dissipating 2.0 watts peak under the following conditions:
t
1
= 1.0 ms, t
2
= 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 R
JA
= 0.22 x 2.0 x 200 = 88
°
C.
For more information, see AN569/D.
The safe operating area curves indicate I

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

is variable depending upon conditions. Pulse curves are valid for
duty cycles to 10% provided T

J(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.
