Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change in

temperature expressed in %/°C or mV/°C.

Rated 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.

Standby Current: The current through the device at rated stand-off voltage.

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.

Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an

Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The
