1N3031B datasheet, circuit
1N3016B thru 1N3051B
This well established zener diode series for the 1N3016 thru 1N3051
JEDEC registration in the metal case DO-13 package provides a glass
hermetic seal for 6.8 to 200 volts. It is also well suited for high-reliability
applications where it is available in JAN, JANTX, and JANTXV military
qualifications. Lower voltages are also available in the 1N3821 thru
1N3830 series (3.3 V to 7.5 V) in the same package (see separate data
sheet). Microsemi also offers numerous other Zener diode products for a
variety of other packages including surface mount.
IMPORTANT: For the most current data, consult MICROSEMI’s website:
Zener Voltage Range: 6.8V to 200V
Hermetically sealed DO-13 metal package
Internally solder-bonded construction.
Also available in JAN, JANTX, JANTXV
qualifications per MIL-PRF19500/115 by adding the
JAN, JANTX, or JANTXV prefixes to part numbers
for desired level of screening, e.g. JANTX1N3016B,
JANTXV1N3051B, etc.
Surface mount also available with 1N3016BUR-1
thru 1N3051BUR-1 series on separate data sheet
Regulates voltage over a broad operating current
and temperature range
Wide selection from 6.8 to 200 V
Tight voltage tolerances available
Low reverse (leakage) currents
Nonsensitive to ESD
Hermetically sealed metal package
Inherently radiation hard as described in Microsemi
MicroNote 050
Operating Junction and Storage Temperatures:

THERMAL RESISTANCE: 50oC/W* junction to lead
at 0.375 inches (10 mm) from body or 110 oC/W
junction to ambient when leads are mounted on FR4
PC board with 4 mm2 copper pads (1 oz) and track
width 1 mm, length 25 mm
DC Power Dissipation*: 1.0 Watt at TL < +125oC 3/8”
(10 mm) from body or 1.0 Watts at TL < +65oC when
mounted on FR4 PC board as described for thermal
resistance above (also see Fig 1)
Forward Voltage @ 200 mA: 1.5 Volts.
Solder Temperatures: 260 o C for 10 s (maximum)
CASE: DO-13 (DO-202AA), welded, hermetically
sealed metal and glass
FINISH: All external surfaces are Tin-Lead (Pb/Sn)
plated and solderable per MIL-STD-750 method
POLARITY: Cathode connected case.
WEIGHT: 1.4 grams.
Tape & Reel option: Standard per EIA-296 (add
“TR” suffix to part number)
See package dimensions on last page
* For further mounting reference, thermal resistance from junction to metal case may be reduced to < 20 oC/W
when mounting DO-13 metal case directly on heat sink.
