SYMBOLS & DEFINITIONS
Symbol
Definition
VRWM Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature
range.
IO
Average Rectified Output Current: Output current averaged over a full cycle with a 50 Hz or 60 Hz sine-wav e input and
a 180 degree conduction ang le.
VF
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
IR
Maximum Leakage Current: The maximum leakage current that will flow at the specified voltage and temperature.
CJ
Junction Capacitance: The junction capacitance in pF at a specified frequency (typically 1 MHz) and specified voltage.
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 recovery decay point after a peak reverse current occurs.
