* 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 equilib­rium 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 ZTA 60Hz rms a.c. current equal

to 10% of l ZT(25
