NOTE 1
No Suffix type numbers are +20% with guaranteed limits for only VZ, lR, and VF.
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 1ZTA 60Hz rms a.c. current equal to
10% of1ZT.
Reverse leakage currents are measured at VRas shown on the table.
VZis the maximum difference between VZat lZTand VZat lZLmeasured
with the device junction in thermal equilibrium.
