3EZ91D datasheet



This is 3 Watt, 91V, Zener Diode.

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.
