Units with “A” suffix are +10% with guaranteed limits for VZ, lR, and VF. Units with guaranteed limits for all six parameters are indicated by a “B” suffix for +5.0% units, “C” suffix for +2.0% and “D” suffix for +1.0%. NOTE 2 Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C. NOTE 3 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT. NOTE 4 NOTE 5 Reverse leakage currents are measured at VR as shown on the table. ∆VZ is the maximum difference between VZ at lZT and VZ at lZL measured with the device junction in thermal equilibrium at the ambient temperature of +25°C +3°C.
