6.2 & 6.55 Volt Temperature Compensated
Surface Mount Zener Reference Diodes
1N821UR thru 1N829AUR-1
(or MLL821 thru MLL829-1)
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 “-1” 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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
• Surface mount equivalent of 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 surface
mount 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.
• 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
• 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
Operating Temperatures: -65
oC to +175oC
Storage Temperatures: -65
oC to +175oC
DC Power Dissipation: 500 mW @ TL = 25
oC and
maximum current IZM of 70 mA. NOTE: For
optimum voltage-temperature stability, IZ = 7.5 mA
(less than 50 mW in dissipated power)
Solder Temperatures: 260
oC for 10 s (max)
CASE: Hermetically sealed glass case. DO-213AA
TERMINALS: Leads, tin-lead plated solderable per
MIL-STD-750, Method 2026
MARKING: Cathode band (except double anode
1N822 and 1N824)
POLARITY: Reference diode to be operated with
the banded end positive with respect to the
opposite end
TAPE & REEL option: Standard per EIA-481-B with
12 mm tape, 2000 per 7 inch reel or 5000 oer 13
inch reel (add “TR” suffix to part number)
WEIGHT: 0.04 grams.
