SYMBOLS & DEFINITIONS
Symbol
Definition
I(BR)
Breakdown Current: T he cur r ent used for measur i ng Break down Voltage V(BR).
ID
Standby Current: The current through the device at rated stand-off voltage.
IPP Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse
current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an
external cause, and it is assumed that its effect will have completely disappeared before the next transient arrives.
P
PP
Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The
impulse power is the maximum-rated value of the product of I
PP
and V
C
.
V(BR)
Breakdown Voltage: The voltage across the device at a specified current I(BR) in the breakdown region.
V
C
Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an
impulse current (IPP) for a specified waveform.
V
WM
Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that
may be continuously applied over the standard operating temperature.
