SILICON 2.0 Watt ZENER DIODES

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. 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

FEATURES

APPLICATIONS / BENEFITS

•

Surface mount equivalent to 1N4728 to 1N4764A
