BR Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature V RWM range. V Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. F Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and I R temperature. C Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage. Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from t the forward direction to the reverse direction and a specified recovery decay point after a peak reverse current is rr reached. o ELECTRICAL CHARACTERISTICS 25 C unless otherwise noted.
