Polarity
R = Anode to Stud
e3 = RoHS compliant
Blank = non-RoHS compliant
Junction Capacitance: The junction capacitance in pF at a specified frequency.
Average Forward Current: The average forward current dc value, no alternating component.
Maximum Forward Surge Current: The forward current, surge peak or rated forward surge current.
I
RM
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
t
rr
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.
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
V
RRM
Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all
non-repetitive transient voltages.
V
RWM
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.
