Temperature Effects
In the leakage region of the AUML suppressor, the device
and shows a temperature dependent affect. In this region
of the AUML are virtually temperature independent.
the suppressor is in a high resistance mode (approaching
the V-I characteristics of the AUML suppressor.
at maximum rated voltage are in the microamp range.
Load Dump Energy Capability
The very high energy absorption capability of the AUML
the automobile is abruptly reduced. The worst case scenario
of this transient occurs when the battery is disconnected
while operating at full rated load. There are a number of
automotive industry, with the most common one being that
recommended by the Society of Automotive Engineers,
speci?cation #SAE J1113. Because of the diversity of these
that energy dissipated by the device itself, independent
handling capability serves as an excellent ?gure of merit for
capability requirement is well within the ratings of all of the
energy, which are applied to the devices. The reliability
information thus generated gives an indication of the
suppressor is achieved by means of a highly controlled
manufacturing process. This technology ensures that a
large volume of suppressor material, with an interdigitated
layer construction, is available for energy absorption in an
extremely small package. Unlike equivalent rated Silicon
TVS diodes, the entire AUML device volume is available to
even energy dissipation ensures that there are lower peak
AUML suppressor.
There are a number of different size devices available in the
AUML Series, each one with a load dump energy rating,
which is size dependent.
Experience has shown that while the effects of a load dump
tranient is of real concern, its frequency of occurrence is
much less than thoe of low energy inductive spikes. Such
low energy inductive spikes may be generated as a result
inherent capability of these devices. As an example of
blowing, etc. It is essential that the suppression technology
selected also has the capability to suppress such transients.
all cases there has been little or no change in the device
Speed of Response
The clamping action of the AUML suppressor depends
on a conduction mechanism similar to that of other
slow response time often associated with transient
parasitic inductance in the package and leads of the
device and less dependent of the basic material (Silicon,
N
response time of any suppressor is its lead induc-tance.
The AUML suppressor is a surface mount device, with no
leads or external packaging, and thus, it has virtually zero
inductance. The actual response time of a AUML surge
suppressor is in the 1 to 5 ns range, more than suf?cient
for the transients which are likely to be encountered in an
automotive environment.
