Figure A
A train of periodical power pulses can be represented by
the model shown in Figure A. Using the model and the
device thermal response, the normalized effective transient
thermal resistance of Figure 12 was calculated for various
duty cycles.
To find
θ
JC
(t), multiply the value obtained from Figure 12
by the steady state value
θ
JC
.
Example:
The 2N5193 is dissipating 50 watts under the following
conditions: t
1
= 0.1 ms, t
p
= 0.5 ms. (D = 0.2).
Using Figure 12, at a pulse width of 0.1 ms and D = 0.2,
the reading of r(t
1
, D) is 0.27.
The peak rise in junction temperature is therefore:
T = r(t) x P

= 0.27 x 50 x 3.12 = 42.2 C
