Description :

The 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zeners provides 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 a moisture classification of “Level 1” with no dry pack required. They may be operated at high maximum dc currents with adequate heat sinking due to their comparatively low thermal resistance design. Microsemi also offers numerous other Zener products to meet higher and lower power applications.
