1N821UR thru 1N829AUR-1
(or MLL821 thru MLL829-1)
SCOTTSDALE DIVISION
6.2 & 6.55 Volt Temperature Compensated
Surface Mount Zener Reference Diodes
DESCRIPTION
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%/
o
C for minimal
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 鈥?1鈥?suffix. This type of
bonded Zener package construction is also available in JAN, JANTX, and
JANTXV military qualifications. Microsemi also offers numerous other
Zener Reference Diode products for a variety of other voltages up to 200 V.
