描述 Description

The popular 1N821 thru 1N829A 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%/o C for minimal voltage change with temperature when operated at 7.5 mA. These glass axialleaded DO-35 reference diodes are optionally available with an internalmetallurgical-bond by adding a “-1” suffix. This type of bonded Zener package construction is also available in JAN, JANTX, and JANTXV military qualifications. Microchip also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.
