Figure 6. Test Circuit Figure 7. Current–Voltage W aveforms
The unclamped inductive switching circuit shown in
Figure 6 was used to demonstrate the controlled avalanche
capability of the new “E’’ series Ultrafast rectifiers. A mercury
switch was used instead of an electronic switch to simulate a
noisy environment when the switch was being opened.
When S1 is closed at t0 the current in the inductor IL ramps
up linearly; and energy is stored in the coil. At t1 the switch is
opened and the voltage across the diode under test begins to
rise rapidly, due to di/dt effects, when this induced voltage
reaches the breakdown voltage of the diode, it is clamped at
BVDUT and the diode begins to conduct the full load current
which now starts to decay linearly through the diode, and
goes to zero at t2.
By solving the loop equation at the point in time when S1 is
opened; and calculating the energy that is transferred to the
diode it can be shown that the total energy transferred is
equal to the energy stored in the inductor plus a finite amount
of energy from the VDD power supply while the diode is in
breakdown (from t1 to t2) minus any losses due to finite com-
ponent resistances. Assuming the component resistive ele-
ments are small Equation (1) approximates the total energy
transferred to the diode. It can be seen from this equation
that if the VDD voltage is low compared to the breakdown
voltage of the device, the amount of energy contributed by
the supply during breakdown is small and the total energy
can be assumed to be nearly equal to the energy stored in
the coil during the time when S1 was closed, Equation (2).
The oscilloscope picture in Figure 8, shows the information
obtained for the MUR8100E (similar die construction as the
MUR1100E Series) in this test circuit conducting a peak cur-
rent of one ampere at a breakdown voltage of 1300 volts,
and using Equation (2) the energy absorbed by the
MUR8100E is approximately 20 mjoules.
Although it is not recommended to design for this condi-
tion, the new “E’’ series provides added protection against
those unforeseen transient viruses that can produce unex-
plained random failures in unfriendly environments.
