1 / 4 page  VOIDLESS-HERMETICALLY-SEALED 5 WATT GLASS ZENER DIODES Microsemi Scottsdale Division 8700 E. Thomas Rd. PO Box 1390, Scottsdale, AZ 85252 USA, (480) 941-6300, Fax: (480) 947-1503 Page 1 Copyright 2005 2-4-2005 REV C SCOTTSD A L E DIVISION 1N4954 thru 1N4996, 1N5968 thru 1N5969, and 1N6632 thru 1N6637 DESCRIPTION APPEARANCE T his 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. 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 • Extremely robust construction • Triple-layer passivation • Internal “Category I” Metallurgical bonds for 1N4954 thru 1N4996, and “Category III” for 1N6632 thru 1N6637 as well as 1N5968 thru 1N5959 • JAN, JANTX, JANTXV, and JANS available per MIL- PRF-19500/356 • Surface mount equivalents also available in a square end-cap MELF configuration with “US” suffix (see separate data sheet for 1N4954US thru 1N4996US, 1N6632US thru 1N6637US and 1N5968US thru 1N5969US • 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 MECHANICAL AND PACKAGING • Operating Temperature: -65oC to +175oC. • Storage Temperature: -65oC to +175oC. • Power Dissipation: 5 Watts @ TA = 25oC • Thermal Resistance: 22oC/W junction to lead at 3/8 inch (10 mm) from body for 1N4954 thru 1N4996 and 30 oC/W for 1N6632 thru 1N6637, 1N5968 thru 1N5969 • Thermal Impedance at 10 ms: 1.8oC/W for 1N4954 thru 1N4996, and 3.0 oC/W for both the 1N6632 thru 1N6637 & 1N5968 thru 1N5969 • Forward Voltage: 1.50 V at 1.0 A • CASE: Hermetically sealed voidless hard glass with Tungsten slugs • TERMINATIONS: Axial-leads are Tin/Lead (Sn/Pb) over Copper except for JANS with solid Silver (Ag) 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 “E” Package |
