Notes:
1. The type numbers listed have zener voltage as whown and have a standard
tolerance on the nominal zener voltage of ±5%. Device of ±2% is indicated
by a "C" instead of a "B".
2. Nominal zener voltages between the voltages shown and tighter voltage, for
detalied information on price, availability and delivery.
3. The zener voltage(VZ) is tested under pulse condition. The measured VZ is
guaranteed to be within specification with device junction in thermal equilibrium.
4. 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 (IZT) is
superimposed to IZT
.
