Test Circuit The unclamped inductive switching circuit shown in Figure 6 was used to demonstrate the controlled ava- lanche 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 is closed at tg the current in the inductor fy ramps up linearly; and energy is stored in the coil. At t the switch is opened and the voitage 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 BVpiT and the diode begins to conduct the full load current 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 $7 is opened; and calculating the energy that is trans- ferred 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 Vpp power sup- ply while the diode is in breakdown (from t1 to tg) minus: Figure 7. Current-Voltage Waveforms any losses due to finite component resistances. Assum- ~ ing 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 Vpp ~ 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 infor- mation obtained for the MUR8100E (similar die construc- tion as the MUR1100E Series) in this test circuit con- ducting 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.
