® MOTOROLA PRECISION REFERENCE DIODES ... designed, manufactured and tested for applications requir· ing a precision voltage reference with ultra·high stability of voltage with time and temperature change. Special test laboratory uses precision measurement equipment, four-terminal (separate contacts for current and voltage) measurement techniques and voltage standards to provide calibration directly traceable to the National Bureau of Standards. MZ600 Series 6.2 VOLTS PRECISION REFERENCE DIODES with CERTIFIED ZENER VOLTAGE-TIME STABILITY ~~~TeST DaTa Every Precision Reference Diode is individually serialized and its test data recorded on a Certificate of Precision that accompanies the device when shipped. This data shows: • Actual device voltage at 168 hour Intervals during verification test • Voltage stability throughout the entire 1000 hour test period • Certification of Precision • All diodes are marked with the device type number and polarity band liB @ D rt--i K L NOTES, 1.

For voltage tolerance, impedance and voltage temperature stability IZT needs to be held to 0.Q1 tolerance only. "Maximum limits for use as a precision reference device. limits are well below the maximum thermal limits. ··VOLTAGE·TEMPERATURE STABILITY: Maximum allow· able voltage change between voltages recorded at 25, 75 and l00'C ambient. VOLTAGE·TIME STABILITY (ll.VZ/1000 Hours). The device voltage is read and recorded initially and at 168 hour Intervals through 1000 hours. The maximum change of voltage between readings, taken at any of the seven paints, must be less than the maximum voltage change per 1000 hour specified as Voltage·Tlme Stability. TURN·ON CHARACTERISTICS Precision Reference Diodes have been tested to determine the behavior of the device under interrupted power operation. To Insure specified performance, adequate time must be allowed for the device and Its environment to reach thermal equilibrium. "Warm·up" time may range from 8 to 24 h.
