† Double Anode; electrical specifications apply under both bias polarities.
NOTES:
1. When ordering devices with tighter tolerances than specified, use a nominal VZ voltage of 6.2 V.
2. Measured by superimposing 0.75mA ac rms on 7.5mA DC @ 25°C.
3. The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the
specified mV change at any discrete temperature between the established limits.
4. Voltage measurements to be performed 15 seconds after application of DC current.
