*Indicates JEDEC Registered Data.
NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of
±5%. C for ±2%, D for ±1%.
NOTE 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 rep-
resentative.
NOTE 3. 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, 3/8from 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.
NOTE 5. 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 registration; however, actual device
capability is as described in Figure 5 of the General Data — DO-41 Glass.
