Notes:
1. Nominal zener voltages between the voltages shown and tighter voltage, for detalied information on
price, availability and delivery.
2. The zener voltage(V
Z
) is tested under pulse condition. The measured V
Z
is guaranteed to be within
specification with device junction in thermal equilibrium.
3. Zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having
an RMS value equal to 10% of the DC zener current (I
ZT
) is superimposed to I
ZT
.
4. Zener voltage has a standard tolerance on the nominal zener voltage of ±5%.
