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.

*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 (I_ZTor I_ZK) is superimposed on I_ZTor I_ZK. 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 25^oC ambient using a square wave or equivalent half-sine wave pulse 1/120 second duration

superimposed on I_ZT

4. Zener voltage (V_Z) is measured at T_L= 25ºC (+8, -2ºC) and 90 seconds after application of dc current.
