VOIDLESS-HERMETICALLY-SEALED
5 WATT GLASS ZENER DIODES
DESCRIPTION
This Zener Voltage Regulator series is military qualified to MIL-PRF-
19500/356 and is ideal for high-reliability applications where a failure
cannot be tolerated. These industry-recognized 5 Watt Zener Voltage
Regulators are hermetically sealed with voidless-glass construction using
an internal metallurgical bond. It includes Zener selections from 3.3 to 390
volts in standard 5% tolerances as well as tighter tolerances identified by
different suffix letters on the part number. They are also available in
surface-mount packages (see separate data sheet for 1N4954US thru
1N4996US, 1N5968US thru 1N5969US, and 1N6632US thru 1N6637US).
Microsemi also offers numerous other Zener products to meet higher and
lower power ratings in both thru-hole and surface mount packages.

APPLICATIONS / BENEFITS
• Regulates voltage over a broad operating current and
temperature range
• Extensive selection from 3.3 to 390 V
• Standard voltage tolerances are plus/minus 5% with
no suffix
• Tight tolerances available in plus or minus 2% or 1%
with C or D suffix respectively
• Flexible axial-lead mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method 1020
• Inherently radiation hard as described in Microsemi
MicroNote 050
MAXIMUM RATINGS
• Operating (TJ) Temperature: -65oC to +175oC.
• Storage Temperature: -65oC to +175oC.
• Power Dissipation: 5 Watts @ TL = 65oC at 3/8 inch
(10 mm) from body for 1N4954 thru 1N4996; and
TL = 25oC for 1N6632 thru 1N6637, 1N5968 thru
1N5969. Derate linearly above these temperatures
to zero at 175oC.
• Thermal Resistance: 22oC/W junction to lead at 3/8
inch (10 mm) from body for 1N4954 thru 1N4996 and
30oC/W for 1N6632 thru 1N6637, 1N5968 thru
1N5969
• Thermal Impedance at 10 ms: 1.8oC/W for 1N4954
thru 1N4996, and 3.0oC/W for both the 1N6632 thru
1N6637 & 1N5968 thru 1N5969
• Forward Voltage: 1.50 V at 1.0 A
MECHANICAL AND PACKAGING
• CASE: Hermetically sealed voidless hard glass with
Tungsten slugs
• TERMINATIONS: Axial-leads are Copper with Tin/Lead
(Sn/Pb) finish. Note: Previous inventory had solid
Silver (Ag) axial-leads and no finish.
• MARKING: Body painted and part number, etc.
• POLARITY: Cathode indicated by band
• Tape & Reel option: Standard per EIA-296
• Weight: 750 mg
