Description

The 1N5388B 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.
