Microsemi 1N821 thru 1N829A-1 DO-7 Zener Reference Diodes Datasheet
The document describes the popular 1N821 thru 1N829 series of Zero-TC Reference Diodes, which provide nominal voltages of 6.2 V and 6.55 V with temperature coefficients as low as 0.0005%/°C when operated at 7.5 mA.
These glass axial-leaded DO-7 reference diodes are available in JAN, JANTX, JANTXV, and JANS military qualifications. The series also offers radiation hardened devices by changing the prefix to 'RH' and is compatible with smaller axial-leaded DO-35 packages.
