2EZ3.6D5 thru 2EZ200D5
DESCRIPTION APPEARANCE
The 2EZ3.6D5 thru 2EZ200D5 series of axial-leaded 2.0 watt Zeners
provides voltage regulation selections with 5% tolerances from 3.6 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 and 2 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.
