2. Suffix denotes Vz tolerance: non suffix ±20%, A suffix ±10%: Ir @ Vr1, Vz, + Vf only.
Suffix B ±5%: Ir @ Vr2, Vz, ∆Vz, Vf, ND.
3. Measured with 10%, 60 Hz AC superimposed on Izt.
4. Measured from 1000 to 3000 Hz.
5. Difference between Vz at Izt and IzL.
6. Forward Voltage (Vf): If = 200mA, Ta = 25°C, Max = 1.1 Vdc.
