1N821 thru 1N829A-1 DO-35
6.2 & 6.55 Volt Temperature Compensated
Zener Reference Diodes
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%/oC for minimal voltage
change with temperature when operated at 7.5 mA. These glass axial-
leaded DO-35 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.

FEATURES
• 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
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. 1N827-2%, 1N829A-1-1%, 1N829-1-1%, etc.
• Flexible axial-lead mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method 1020
• Typical low capacitance of 100 pF or less
MAXIMUM RATINGS
• Operating Temperatures: -65oC to +175oC
• Storage Temperatures: -65oC to +175oC
• DC Power Dissipation: 500 mW @ TL = 25oC 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: 260oC for 10 s (max)
MECHANICAL AND PACKAGING
