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
A 60Hz rms a.c. current equal to
10% of1
ZT.
NOTE 4 Reverse leakage currents are measured at V
R
as shown on the table.
NOTE 5 ∆V
