Notes:1. Tolerance and voltage designation: the type numbers listed have zener voltage as shown.
2. Specials available include: nominal zener voltages between the voltages shown and
tighter voltage, for detailed information on price, availability and delivery.
3. Zener voltage (VZ) measurement: the zener voltage is measured under pulse conditions
such that TJ is more than 2oC above TA.
4. Zener impedance (ZZ) derivation: 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. Version: A07
