11.7 VOLT TEMPERATURE
COMPENSATED ZENER REFERENCE DIODES
• Standard reference voltage of 11.7 V ±5% with tighter tolerance also available
• Available Non-RoHS (standard) or RoHS compliant (add PBF suffix).
• Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number.

Note 1: For tighter voltage tolerances, add a hyphenated suffix to the part number for desired tolerance at the end of the part number.
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 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.
