Explanation of Terms
Maximum Continuous DC Working Voltage (*V
be applied, up to the maximum operating temperature
reference test point for leakage current and is always less
than the breakdown voltage of the device.
Load Dump Energy Rating *W
This is the actual energy the part is rated to dissipate
Maximum Clamping Voltage *V
This is the peak voltage appearing across the suppressor
when measured at conditions of specified pulse current
that the peak current and peak voltage may not necessarily
be coincidental in time.
Leakage Current *I
In the nonconducting mode, the device is at a very
system. The leakage current drawn at this level is very
low (<25μ
that, when operated up to its maximum temperature,
Nominal Voltage *V
This is the voltage at which the AUML enters its
conduction state and begins to suppress transients.
In the automotive environment this voltage is
