NOTE 1. TOLERANCES
Suffix 5 indicates 5% tolerance. Any other tolerance will be considered as a special device.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when measured at 40 ms
±10
ms 3/8″ from the diode
body, and an ambient temperature of 25°C (+8°C, –2°C)
NOTE 3. ZENER IMPEDANCE (Z Z) 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 (i r) 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°C
±1°C,
3/8″ from the diode body.
NOTE 4. ZENER IMPEDANCE (Z Z) 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.
