SYMBOLS & DEFINITIONS
Definition
Junction Capacitance: The junction capacitance in pF at a specified frequency (typically 1MHz) and specified voltage.
Maximum Forward Current: The maximum forward current dc value, no alternating component.
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Junction Temperature: The temperature of a semiconductor junction.
Forward Voltage: The forward voltage the device will exhibit at a specified current (typically shown as maximum
value).
Reverse Voltage: The reverse voltage dc value, no alternating component.
