NOTE 1. TOLERANCES
NOTE 3. ZENER VOLTAGE (V ) MEASUREMENT
Z
Suffix 5 indicates 5% tolerance. Any other tolerance will be considered as a special device.
Motorola guarantees the zener voltage when meausred at 90 seconds while maintaining the
lead temperature (T ) at 30°C ±1°C, 3/8″ from the diode body.
NOTE 2. ZENER VOLTAGE (V ) MEASUREMENT
Z
L
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 4. ZENER IMPEDANCE (Z ) DERIVATION
Z
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-

Nominal zener voltages between those shown. Tight voltage tolerances such as ±1% and
±2%. Consult factory.
