Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Forward biasing either diode will affect the operation of the other
diode.
Note 3: This parameter guaranteed by “reverse breakdown voltage change
with current” test.
