The 1N821UR thru 1N829AUR-1 series of surface mount Zero-TC
Reference Diodes provides a selection of both 6.2 V and 6.55 V nominal
voltages and temperature coefficients to as low as 0.0005%/
voltage change with temperature when operated at 7.5 mA. These glass
surface mount DO-213AA (MELF) reference diodes are optionally available
with an internal-metallurgical-bond by adding a “-1” suffix as well as RoHS
Compliant with an e3 suffix.
construction is also available in JAN, JANTX, and JANTXV military
qualifications (RoHS Compliant option not applicable).
offers numerous other Zener Reference Diode products for a variety of
other voltages up to 200 V.
• Surface mount equivalent of JEDEC registered
• Internal metallurgical bond option available by adding
• Reference voltage selection of 6.2 V & 6.55 V +/-5%
• 1N821, 823, 825, 827 and 829 also have surface
• RoHS Compliant devices available by adding an e3
• Axial-leaded equivalents also available in DO-35 or
• JANS equivalent available in DO-213AA via SCD
1N821 thru 1N829 series
a “-1” suffix
with further tight tolerance options at lower voltage
mount qualification to MIL-PRF-19500/159 by adding
the JAN, JANTX, or JANTXV prefixes to part
numbers a well as the “-1” suffix; e.g. JANTX1N829-
1, etc.
