Mechanical & Packaging CASE: Ceramic THERMALS: Gold plating over nickel under plate. TAPE & REEL option: Standard per EIA-4180. Consult factory for quantities. WEIGHT: < 0.04 Grams. Symbols & Definitions Symbol Definitions IR Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. IO Average Rectified Forward Current: The output current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave input and a 180 degree conduction angle. trr 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. VF VR VRWM Forward Voltage: The forward voltage the device will exhibit at a specified current (typically shown as maximum value). Reverse Voltage: The reverse voltage de value, no alternating component. 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.
