2. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)
The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.
3. 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 YEASHIN representative.
4. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (TL) at 30°C
±1°C and 3/8” lead length.
5. 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.
6. SURGE CURRENT (Ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of ½ square
wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current IZT per JEDEC registration;
however, actual device capability is as described in figure 5 of the General Data DO-41 Glass.
