NOTE:
1/ Suffix A ± 5%,
B ± 2%,
C ± 1%
C ± 2%,
3/ Suffix A ± 0.2V, B ± 0.15V, C ± 0.11V
Note (1): Zener impedance is derived by superimposing on Izt a 60Hz rms a.c. current equal to 10% of Izt
2/ Suffix A ± 10%, B ± 5%,
D ± 1%
MOUNTING POSITION: Any
Note (2): ΔVz is the difference between Vz @ IzL and IzH measured with the device junction in thermal equilibrium at the ambient temperature of
+25°C ±3°C
Note (3): Measured from 1000 to 3000 Hz
