DESCRIPTION
APPEARANCE
The SMBJ5333-5388B or SMBG5333-5388B series of surface mount 5.0
watt Zeners provides voltage regulation in a selection from 3.3 to 200 volts
with different tolerances as identified by suffix letter on the part number. It is
equivalent to the JEDEC registered 1N5333 thru 1N5388B with identical
electrical characteristics and testing as well as RoHS Compliant with an e3
suffix. It is available in J-bend design (SMBJ) with the DO-214AA package
for greater PC board mounting density or in Gull-wing design (SMBG) in the
DO-215AA for visible solder connections. These plastic encapsulated
Zeners have a moisture classification of Level 1 with no dry pack required
and are also available in military equivalent screening levels by adding a
prefix identifier as further described in the Features section. Microsemi also
offers numerous other Zener products to meet higher and lower power
applications.
NOTE: All SMB series are
equivalent to prior SMS package
identifications.
