Maximum Peak Forward Current: The peak total value of the forward current dc value. Maximum Forward Surge Current: The forward current, surge peak or rated forward surge current. Average Rectified Output Current: The output current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave input and a 180 degree conduction angle. Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs. Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. Reverse Voltage: The reverse voltage dc value, no alternating component. Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all non-repetitive transient voltages. Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV.
