1N821UR thru 1N829AUR-1
(or MLL821 thru MLL829-1)
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%/oC 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 â-1â 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.

APPEARANCE
DO-213AA
FEATURES
⢠Surface mount equivalent of JEDEC registered
1N821 thru 1N829 series
⢠Internal metallurgical bond option available by adding
a â-1â 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 surface
mount qualification to MIL-PRF-19500/159 by adding
the JAN, JANTX, or JANTXV prefixes to part
numbers a well as the â-1â suffix; e.g. JANTX1N829-
1, etc.
⢠Axial-leaded equivalents also available in DO-35 or
DO-7 without the UR suffix (see separate data sheet)
including military qualifications up to JANS for DO-7
(see separate data sheet)
⢠JANS equivalent available in DO-213AA via SCD
APPLICATIONS / BENEFITS
⢠Provides minimal voltage changes over a broad
temperature range
⢠For instrumentation and other circuit designs
requiring a stable voltage reference
⢠Maximum temperature coefficient selections available
from 0.01%/ºC to 0.0005%/ºC
⢠Tight reference voltage tolerances available with
center nominal value of 6.15 V by adding designated
tolerance such as 1%, 2%, 3%, etc. after the part
number for identification
e.g. 1N827UR-2%, 1N829AUR-1-1%, etc.
⢠Small surface-mount footprint
⢠Nonsensitive to ESD per MIL-STD-750 Method 1020
⢠Typical low capacitance of 100 pF or less
MAXIMUM RATINGS
