1N821A General Description
The popular 1N821 thru 1N829 series of 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%/oC for minimal voltage change with temperature when operated at 7.5 mA. These glass axialleaded DO-7 reference diodes are also available in JAN, JANTX, JANTXV, and JANS military qualifications. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.
