Definition
CJ
Junction Capacitance: The junction capacitance in pF at a specified frequency (typically 1MHz) and specified voltage.
IF
Forward Current: The forward current dc value, no al ternating component.
IR
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
TJ
Junction Temperature: The temperature of a semiconductor junction.
VF
Forward Voltage: The forward voltage the device will exhibit at a specified current (typical ly shown as maximum
value).
VR
Reverse Voltage: The reverse voltage dc value, no al ternating component.
