Switch-mode
Power Rectifiers
NHP820LFS, NRVHP820LFS
This LFPAK ultrafast rectifier provides fast switching performance
with soft recovery in a compact thermally efficient package. The
LFPAK package provides an excellent alternative to the DPAK,
offering thermal performance nearly as good in a package occupying
less than half the board space. Its low profile makes it a good option
for flat panel display and other applications with limited vertical
clearance. The device offers low leakage over temperature making it a
good match for applications requiring low quiescent current.

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 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 unclamped inductive switching circuit shown in
Figure 9 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
