C Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage I Breakdown Current: The current used for measuring Breakdown Voltage V . (BR) (BR) I Standby Current: The current through the device at rated stand-off voltage. D I Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse PP 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 Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The PP impulse power is the maximum-rated value of the product of I and V . PP C V Breakdown Voltage: The voltage across the device at a specified current I in the breakdown region. (BR) (BR) V Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an C impulse current (I ) for a specified waveform. PP V Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that WM may be continuously applied over the standard operating temperature.
