1 / 4 page VOIDLESS-HERMETICALLY-SEALED Surface Mount 5 WATT GLASS ZENER SCOTTSD A L E DIVISION 1N4954US thru 1N4996US, 1N5968US thru 1N5969US, and 1N6632US thru 1N6637US DESCRIPTION APPEARANCE T his surface mount 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 axial-leaded packages for thru hole mounting by deleting the “US” suffix (see separate data sheet for 1N4954 thru 1N4996, 1N5968 thru 1N5969, and 1N6632 thru 1N6637). Microsemi also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages. “E” Package (or “D-5B”) IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • Popular JEDEC registered series • Voidless hermetically sealed glass package • Triple-layer passivation • Internal “Category I” Metallurgical bonds for 1N4954US thru 1N4996US, and “Category III” for 1N6632US thru 1N6637US as well as 1N5968US thru 1N5959US • JAN, JANTX, JANTXV, and JANS available per MIL- PRF-19500/356 • Axial-leaded equivalents (see separate data sheet for 1N4954 thru 1N4996, 1N6632 thru 1N6637 and 1N5968 thru 1N5969) • 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 • Extremely robust construction • Nonsensitive to ESD per MIL-STD-750 Method 1020 • Inherently radiation hard as described in Microsemi MicroNote 050 MAXIMUM RATINGS MECHANICAL AND PACKAGING • Operating Temperature: -65oC to +175oC. • Storage Temperature: -65oC to +175oC. • Power Dissipation: 5 Watts @ TEC = 125oC and derate linearly at 0.1 W/ oC above TEC = 125oC to zero at 175 oC • Thermal Resistance: 7oC/W junction to end cap for 1N4954US thru 1N4996US and 10 oC/W for 1N6632US thru 1N6637US as well as 1N5968US thru 1N5969US • Thermal Impedance at 10 ms: 1.8oC/W for 1N4954US thru 1N4996US, and 3.0 oC/W for both the 1N6632US thru 1N6637US & 1N5968US thru 1N5969US • Forward Voltage: 1.50 V at 1.0 A • CASE: Hermetically sealed voidless hard glass with Tungsten slugs • TERMINATIONS: End caps are solid Silver (Ag) with Tin/Lead (Sn/Pb) finish • MARKING: None • POLARITY: Cathode indicated by band • Tape & Reel option: Standard per EIA-481-B • Weight: 539 mg Microsemi Scottsdale Division 8700 E.
