NOTE 1 The CDI type numbers shown above have a Zener voltage tolerance of +5.0%.
Nominal Zener voltage is measured with the device junction in thermal
equilibrium at an ambient temperature of 25°C + 3°C. "C" suffix denotes a + 2%
tolerance and "D" suffix denotes a + 1% tolerance.
NOTE 2 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of IZT.
