1) Tested with pulses tp=20 ms.
2) SPECIALS AVAILABLE INCLUDE: Nominal zener voltages between the voltages shown and tighter voltage tolerances.
For detailed information on price, availability, and delivery, contact your nearest Motorola representative. ZENER VOLTAGE
(VZ) MEASUREMENT：Motorola guarantees the zener voltage when measured at 90 seconds while maintaining the
lead temperature (TL) at 30°C ± 1°C, 3/8, from the diode body.
3) Valid provided that leads are kept at ambient temperature at a distance of 8 mm form case.
4)
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.
