1N5333B thru 1N5388B, e3
Silicon 5 Watt Zener Diodes
SCOTTSDALE DIVISION
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.
