Definition
αV(BR)
Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change i n
temperature that cau sed it expressed in %/°C or mV/°C.
C
Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage
I(BR)
Breakdown Current: The current used for measuring Breakdown Voltage V(BR) .
ID
Standby Current: The current through the device at rated stand-off voltage.
I
PP
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 i s usually due to an
external cause, and it is assumed that its effect wi ll 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 (I
PP
) for a specified waveform.
V
WM
Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positi ve cathode-to-anode voltage that
may be continuously applied over the standard operating temperature.
