SYMBOLS & DEFINITIONS
Definition
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
Working Peak Voltage: The maximum peak voltage that can be applied over the operating temperature range.
This is also referred to as Standoff Voltage.
Maximum Standoff Current: The maximum current that will flow at the specified voltage and temperature.
Maximum clamping voltage at specified I_PP (Peak Pulse Current) at the specified pulse conditions.
Peak Pulse Power: The peak power dissipation resulting from the peak impulse current I_PP.

NOTE: Peak power defined as peak voltage times peak current
Peak Value
I_PP
Pulse time duration (tp) is
defined as that point where
I_P decays to 50% of peak
value (I_PP).
time (t) in milliseconds
