Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not normal
operating conditions) and are not valid simultaneously. If these limits are exceeded,
device functional operation is not implied, damage may occur and reliability may
be affected.

A train of periodical power pulses can be represented by
the model as shown in Figure 9. Using the model and the de-
102 ICEO vice thermal response the normalized effective transient
thermal resistance of Figure 8 was calculated for various
101 duty cycles.
To find ZqJA(t), multiply the value obtained from Figure
100 ICBO 8 by the steady state value RqJA.
AND Example:
10−1
ICEX @ VBE(off) = 3.0 Vdc
The MPS3904 is dissipating 2.0 watts peak under the follow-
ing conditions:
10−2 t1 = 1.0 ms, t2 = 5.0 ms. (D = 0.2)
−40 −20 0 + 20 + 40 + 60 + 80 + 100 + 120 + 140 + 160 Using Figure 8 at a pulse width of 1.0 ms and D = 0.2, the
TJ, JUNCTION TEMPERATURE (°C)
reading of r(t) is 0.22.
Figure 10.
The peak rise in junction temperature is therefore
DT = r(t) x P(pk) x RqJA = 0.22 x 2.0 x 200 = 88°C.

The data of Figure 11 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 8. At high case or
ambient temperatures, thermal limitations will reduce the
40 power that can be handled to values less than the limitations
imposed by second breakdown.
