Note 1. For devices with tighter tolerances, use a nominal voltage of 9.2V and add a hyphenated suffix to the part number for desired tolerance at the end of the part number,
ie. – 2%
Note 2. Measured by superimposing 0.75mA ac rms on 7.5 mA dc @ 25°C
Note 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
Note 4. Voltage measurements to be performed 15 seconds after application of dc current
