NOTE 1. TOLERANCES
Suffix 5 indicates 5% tolerance. Any other tolerance will be considered as a special device.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
±
10 ms 3/8
″
from the diode
body, and an ambient temperature of 25
°
C (+8
°
C, –2
°
C)
NOTE 3. 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.
NOTE 4. SURGE CURRENT (ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-
verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-
tion superimposed on the test current, IZT, per JEDEC standards, however, actual device ca-
pability is as described in Figure 3 of General Data sheet for Surmetic 30s.
NOTE 5. SPECIAL SELECTIONS AVAILABLE INCLUDE:
Nominal zener voltages between those shown. Tight voltage tolerances such as
±
1% and
±
2%. Consult factory.
NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when meausred at 90 seconds while maintaining the
lead temperature (TL) at 30
°

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.
