Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Forward biasing either diode will affect the operation of the other
diode.
Note 3: This parameter guaranteed by “reverse breakdown change with
current” test.
Note 4: For the LT1034-1.2: 20µA ≤ I_R ≤ 2mA. For the LT1034-2.5:
30µA ≤ I_R ≤ 2mA.
