NOTE 1 The JEDEC type numbers shown above have a Zener voltage tolerance of + 5% of the nominal Zener voltage. Vz is measured with the device junction in thermal equilib- rium at an ambient themperature of 25°C + 3°C. A “C” suffix denotes a +2% tolerance and a “D” suffix denotes a +1% tolerance. NOTE 2 Zener impedance is derived by superimposing on l ZT A 60Hz rms a.c. current equal to 10% of l ZT (25 µ A a.c.)
