DESCRIPTION
APPEARANCE
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 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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
APPLICATIONS / BENEFITS
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
RoHS compliant devices available by adding “e3” suffix
Regulates voltage over a broad operating current
and temperature range
