Definitions
IR
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
IO
Average Rectified Forward 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.
trr
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.
VF
VR
VRWM
Forward Voltage: The forward voltage the device will exhibit at a specified current (typically shown as maximum
value).
Reverse Voltage: The reverse voltage de value, no alternating component.
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.
