PART NOMENCLATURE JAN 1N4148 UB CA Reliability Level Polarity JAN = JAN level CA = Common Anode JANTX = JANTX level CC = Common Cathode JANTXV = JANTXV level D = Doubler Blank = Commercial grade Blank = Unidirectional JEDEC type number Surface Mount package (see Electrical Characteristics table) Common Anode Unidirectional Doubler Common Cathode SYMBOLS & DEFINITIONS Symbol Definition I Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. R 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. t Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from rr the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs. V Forward Voltage: The forward voltage the device will exhibit at a specified current (typically shown as maximum F value). V Reverse Voltage: The reverse voltage dc value, no alternating component. R Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range V RWM excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV.
