* JEDEC Registered Data.
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.)
