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.
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.
