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 25C + 3C.
NOTE 3
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of1ZT.
NOTE 4
Reverse leakage currents are measured at VR as shown on the table.
NOTE 5
VZ is the maximum difference between VZ at lZT and VZ at lZL measured
with the device junction in thermal equilibrium.
