PART NOMENCLATURE JAN 1N6391 e3 Reliability Level RoHS Compliance JAN = JAN level e3 = RoHS compliant (available JANTX = JANTX level on commercial grade only) JANTXV = JANTXV level Blank = non-RoHS compliant JANS = JANS level Blank = Commercial JEDEC type number (see Electrical Characteristics table) SYMBOLS & DEFINITIONS Symbol Definition f Frequency Forward Current: The current flowing from the external circuit into the anode terminal. Also see first page ratings and I FM test conditions for I with 50% duty cycle square wave. FM Surge Peak Forward Current: The forward current including all nonrepetitive transient currents but excluding all I FSM repetitive transients (ref JESD282-B). Average Rectified Forward Current: The output current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave I O input and a 180 degree conduction angle. V Maximum Forward Voltage FM V Reverse Voltage: A positive dc cathode-anode voltage below the breakdown region. R Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all V RRM non-repetitive transient voltages. Non-Repetitive Peak Inverse Voltage: The peak reverse voltage including all non-repetitive transient voltages but V RSM excluding all repetitive transient voltages. Working Peak Reverse Voltage: The peak voltage excluding all transient voltages (ref JESD282-B). Also sometimes V RWM known historically as PIV.
