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

temperature that caused it expressed in %/°C or mV/°C.

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

Surge Peak Forward Current: The forward current including all nonrepetitive transient currents but excluding all

repetitive transients (ref JESD282-B).

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.

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

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

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.
