DESCRIPTION
APPEARANCE
The SMBJ4728A-4764A and SMBG4728A-4764A series of surface mount
2.0 watt Zeners provides voltage regulation in a selection from 3.3 to 100
volts with different tolerances as identified by suffix letter on the part
number as well as RoHS Compliant with an e3 suffix. This surface mount
product series with lower thermal resistance features is equivalent to the
JEDEC registered 1N4728 thru 1N4764A with identical electrical
characteristics except it is rated at 2.0 W instead of 1.0 W. 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. 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

*JEDEC Registered Data
NOTES:
1. The JEDEC type numbers shown with an A suffix have a 5% tolerance on nominal zener voltage. No suffix signifies a 10% tolerance,
C signifies 2%, and D signifies 1% tolerance. Also add a P suffix for designating plastic construction (or G suffix for glass body). Add
an e3 suffix for RoHS compliant devices.
2. The Zener impedance is derived from the 60 Hz ac voltage that results when an ac current having an rms value equal to 10% of the dc
Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to ensure a sharp knee on the
breakdown curve and eliminate unstable units. See MicroNote 202 for zener impedance variation with different operating currents.
3. The reverse surge current is measured at 25oC ambient using a square wave or equivalent half-sine wave pulse 1/120 second duration
superimposed on IZT
.
4. Zener voltage (VZ) is measured at TL = 25ºC (+8, -2ºC) and 90 seconds after application of dc current.
