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 1
ZT
A60Hz rms a.c. current equal to 10% of 1
ZT.
NOTE 4 Reverse leakage currents are measured at V
R
as shown on the table.
NOTE 5 ∆VZ is the maximum difference between VZ at lZTand V
Z
at l
ZL
measured with
the device junction in thermal equilibrium at the ambient temperature of +25°C +3°C.
