DESCRIPTION

APPEARANCE

The 1N5333-5388B JEDEC registered series of axial-leaded 5.0 watt

Zeners provides voltage regulation in a selection from 3.3 to 200 volts with

different tolerances as identified by specific suffix letter on the part number.

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

with adequate heat sinking with their comparatively low thermal resistance

design.

Microsemi also offers numerous other Zener products to meet

higher and lower power applications.
