Notes:
1. Tolerance and type number designation the type numbers listed indicate a tolerance of 5%
2. Zener voltage (V
z
) measurement
Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature 25°C
3. Zener impedance (Z
z
) derivation : Z
ZT
and Z
ZK
are measured by dividing the AC voltage
drop across the device by the AC current applied.
The specified limits are for I
z
(AC) = 0.1 I
z
(DC) with the AC frequency = 60 Hz
