NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT

Motorola guarantees the zener voltage when meausred at 90 seconds while maintaining the

lead temperature (TL) at 30°C ±1°C, 3/8″ from the diode body.

NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION

The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-

rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed

on IZT or IZK.
