Figure 6. Test Circuit
Figure 7. Current–Voltage Waveforms
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.
component resistances. Assuming the component resistive
elements are small Equation (1) approximates the total
energy transferred to the diode. It can be seen from this
equation that if the V
voltage is low compared to the
DD
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
When S is closed at t the current in the inductor I ramps

up linearly; and energy is stored in the coil. At t 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
Equation (2).
The oscilloscope picture in Figure 8. , shows the
information obtained for the MUR8100E (similar die
construction as the MUR4100E Series) in this test circuit
conducting a peak current 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
condition, the new “E’’ series provides added protection
against those unforeseen transient viruses that can produce
unexplained random failures in unfriendly environments.

which now starts to decay linearly through the diode, and
goes to zero at t .

By solving the loop equation at the point in time when S

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 V power supply while the diode is in
