Modeling Reverse Energy Characteristics
of Power Rectifiers
ABSTRACT
applied to devices used in this switching power circuitry.
This technology lends itself to lower reverse breakdown
voltages. This combination of high voltage spikes and low
reverse breakdown voltage devices can lead to reverse
energy destruction of power rectifiers in their applications.
This phenomena, however, is not limited to just Schottky
technology.
In order to meet the challenges of these situations, power
semiconductor manufacturers attempt to characterize their
devices with respect to reverse energy robustness. The
typical reverse energy specification, if provided at all, is
usually given as energy−to−failure (mJ) with a particular
inductor specified for the UIS test circuit. Sometimes the
peak reverse test current is also specified. Practically all
reverse energy characterizations are performed using the
UIS test circuit shown in Figure 10. Typical UIS voltage and
current waveforms are shown in Figure 11.
In order to provide the designer with a more extensive
characterization than the above mentioned one−point
approach, a more comprehensive method for characterizing
these devices was developed. A designer can use the given
information to determine the appropriateness and safe
operating area (SOA) of the selected device.
Power semiconductor rectifiers are used in a variety of
applications where the reverse energy requirements often
vary dramatically based on the operating conditions of the
application circuit. A characterization method was devised
using the Unclamped Inductive Surge (UIS) test technique.
By testing at only a few different operating conditions
(i.e. different inductor sizes) a safe operating range can be
established for a device. A relationship between peak
avalanche current and inductor discharge time was
established. Using this relationship and circuit parameters,
the part applicability can be determined. This technique
offers a power supply designer the total operating conditions
for a device as opposed to the present single−data−point
approach.
INTRODUCTION
In today’s modern power supplies, converters and other
switching circuitry, large voltage spikes due to parasitic
inductance can propagate throughout the circuit, resulting in
catastrophic device failures. Concurrent with this, in an
effort to provide low−loss power rectifiers, i.e., devices with
lower forward voltage drops, Schottky technology is being

Example Application
The device used for this example was an MBR3035CT,
which is a 30 A (15 A per side) forward current, 35 V reverse
breakdown voltage rectifier. All parts were tested to
destruction at 25C. The inductors used for the
characterization were 10, 3.0, 1.0 and 0.3 mH. The data
recorded from the testing were peak reverse current (Ip),
peak reverse breakdown voltage (BVR), maximum
withstand energy, inductance and inductor discharge time
(see Table 1). A plot of the Peak Reverse Current versus
Time at device destruction, as shown in Figure 12, was
generated. The area under the curve is the region of lower
reverse energy or lower stress on the device. This area is
known as the safe operating area or SOA.

Utilizing the UIS test circuit in Figure 10, devices are
tested to failure using inductors ranging in value from 0.01
to 159 mH. The reverse voltage and current waveforms are
acquired to determine the exact energy seen by the device
and the inductive current decay time. At least 4 distinct
inductors and 5 to 10 devices per inductor are used to
generate the characteristic current versus time relationship.
This relationship when coupled with the application circuit
conditions, defines the SOA of the device uniquely for this
application.

Traditionally, power rectifier users have been supplied
with single−data−point reverse−energy characteristics by
the supplier’s device data sheet; however, as has been shown
here and in previous work, the reverse withstand energy can
vary significantly depending on the application. What was
done in this work was to create a characterization scheme by
which the designer can overlay or map their particular
requirements onto the part capability and determine quite
accurately if the chosen device is applicable. This
characterization technique is very robust due to its statistical
approach, and with proper guardbanding (6s) can be used to
give worst−case device performance for the entire product
line. A “typical” characteristic curve is probably the most
applicable for designers allowing them to design in their
own margins.
The procedure to determine if a rectifier is appropriate,
from a reverse energy standpoint, to be used in the
application circuit is as follows:
a. Obtain “Peak Reverse Current versus Time” curve
from data book.
b. Determine steady state operating voltage (OV) of
circuit.
c. Determine parasitic inductance (L) of circuit section of
interest.
d. Obtain rated breakdown voltage (BVR) of rectifier
from data book.
