1. Suffix denotes Vz tolerance: non suffix ±20%, A suffix ±10%: Ir @ Vr1, Vz, + Vf only.
Suffix B ±5%: Ir @ Vr2, Vz, ∆Vz, Vf, ND.
2. Measures with 10%, 60 Hz AC superimposed on Izt.
3. Measured from 1000 to 3000 Hz.
4. Difference between Vz at Izt and IzL.
5. Forward Voltage (Vf): If = 200mA, Ta = 25°C, Max = 1.1 Vdc.
6. Package Style DO-7
