max V CC , min coil resistance and usually minimum
temperature) that the MDC3105 will have to drive
and make sure it is less than the max rated current.
For pulsed operation, use the Transient Thermal
Response of Figure 12 and the instructions with it
to determine the maximum limit on transistor power
dissipation for the desired duty cycle and
temperature range.
Use Figures 10 and 11 with the SOA notes above to
insure that instantaneous operation does not push
the device beyond the limits of the SOA plot.
While keeping any V O(sat) requirements in mind,
determine the max input current needed to achieve
that output current from Figures 2 and 6.
For levels of input current below 100 m A, use the
input threshold curves of Figure 4 to verify that

For levels of input current above 100 m A, enter
Figure 3 using that max input current and determine
the input voltage required to drive the MDC3105
from the solid V in versus I in line. Select a suitable
drive source family from those whose dotted lines
cross the solid input characteristic line to the right
of the I in , V in point.
Using the max output current calculated in step 1,
check Figure 7 to insure that the range of Zener
clamp voltage over temperature will satisfy all
system and EMI requirements.
Using Figures 8 and 9, insure that “OFF” state
leakage over temperature and voltage extremes does
not violate any system requirements.
Review circuit operation and insure none of the
device max ratings are being exceeded.
