SYMBOLS & DEFINITIONS
Definition
Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage.
frequency
Forward Current: The dc current flowing from the external circuit into the anode terminal.
Surge Peak Forward Current: The forward current including all nonrepetitive transient currents but excluding all
repetitive transients (ref JESD282-B)
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 dc current flowing from the external circuit into the cathode terminal at the specified voltage V
R
.
Working Peak Reverse Voltage: The peak voltage excluding all transient voltages (ref JESD282-B). Also sometimes
known historically as PIV.
Forward Voltage: A positive dc anode-cathode voltage the device will exhibit at a specified forward current.
Reverse Voltage: A positive dc cathode-anode voltage below the breakdown region.
