SMBJ5333 thru SMBJ5388B, e3
SMBG(J)533–5388B, e3
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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

NOTE 1: Devices listed above with B suffix have ±5% tolerance, A suffix designates ±10% tolerance, C suffix designates ±2%
tolerance, and D designates ±1% toler ance.
NOTE 2: Zener voltage (Vz) is measured at TL = 25oC (+8, -2oC). Voltage measurement to be performed 40 ±10 mi lliseconds
after application of dc current.
NOTE 3: The zener impedance is derived from 1 kHz ac voltag e resulting from an ac current modulation having an rms value
equal to 10% of the dc zener current (IZT or IZK) superimposed on IZT or IZK. See Micro Note 202 for zener imped ance
variation with different operating currents.
NOTE 4: The maximum current (IZM) shown is for a ±5% tolerance devices. The IZM for other tolerances can be calculated using
the formula: IZM = P/VZM whe re V ZM is the VZ at the high end of the voltage tolerance specified and P is the rated po wer
for the method of mounting.
NOTE 5: The surge current (IZSM) is specified as the maximum peak of a non-recurrent half-sine wave of 8.3 ms duration.
NOTE 6: Voltage regulation (VZ) is the difference between the voltage measured at 10% and 50% of IZM.

(#313298)
Zener Voltage Regulator Diode
Description :
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.
