PART NOMENCLATURE 1N3879 R (e3) JEDEC Registered Number (see Electrical Characteristics table) RoHS Compliance e3 = RoHS compliant Blank = non-RoHS compliant Polarity R = Anode to Stud Blank = Cathode to Stud SYMBOLS & DEFINITIONS Definition Symbol CJ IF(AV) IFSM IRM trr VFM VRRM VRWM 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. Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. 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. Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all non-repetitive transient voltages. 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.
