3. ZENER VOLTAGE (VZ) MEASUREMENT

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 (ZZ) DERIVATION

The 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 or IZK) is superimposed on IZT or IZK.
