1N827/TR [Microchip]

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.

JEDEC registered 1N821 thru 1N829 series

Internal metallurgical bond option available by adding a “-1” suffix

Reference voltage selection of 6.2 V & 6.55 V +/-5% with further tight tolerance options at lower voltage

1N821, 823, 825, 827 and 829 also have 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

Military surface mount equivalents also available in DO-213AA by adding UR-1 suffix and the JAN, JANTX, and JANTXV prefix, e.g

JANTX1N829UR-1 (see separate data sheet)

Also available in DO-7 package including military qualifications up to JANS (see separate data sheet)

JANS equivalent available in DO-35 via SCD
