DESCRIPTION
The 3EZ3.9D5 thru 3EZ200D5 series of axial-leaded 3.0 watt Zeners provides voltage regulation selections with 5% tolerances from 3.9 to 200 volts in a DO-41 plastic package size. Other Zener voltage tolerances are also available by changing the suffix number to the tolerance desired such as 1, 2 3, or 4 for tighter tolerances or 10 for wider tolerance. These plastic encapsulated Zeners have moisture classification of Level 1 with no dry pack required and are also available in various military equivalent screening levels by adding a prefix identifier as also described in the Features section. They may be operated at high maximum dc currents or full power rating with adequate heat. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

FEATURES
• Zener voltage available 3.9 V to 200 V
• Standard voltage tolerances are plus/minus 5%
   with a 5 suffix and 10 % with 10 suffix
   identification
• Tight tolerances available in plus or minus 4%,
   3%, 2% or 1% with 4, 3, 2, or 1 suffix respectively
• Options for screening in accordance with MIL
   PRF-19500 for JAN, JANTX, JANTXV, and JANS
   are available by adding MQ, MX, MV, or MSP
   prefixes respectively to part numbers.
• Surface mount equivalents available as
   SMBJ3EZ3.9D5 to SMBJ3EZ200D5 in the DO-
   214AA package, or SMBG3EZ3.9D5 to
   SMBG3EZ200D5 in the DO-215AA package
  
APPLICATIONS / BENEFITS
• Regulates voltage over a broad operating current and temperature range
• 3 W capability in relatively small DO-41 package size
   when adequately heat sunk (see Figure 1)

• Flexible axial-lead mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method 1020
• Withstands surge stresses
• High specified maximum current (IZM) when adequately heat sunk
• Moisture classification is Level 1 per IPC/JEDEC
   J-STD-020B with no dry pack required
