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 NOTE: All SMB series are equivalent Zener products to meet higher and lower power applications. to prior SMS package identifications.

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 or I ) is superimposed on I or I . Zener impedance is measured at two points to ensure a sharp knee on the ZT ZK ZT ZK breakdown curve and eliminate unstable units. See MicroNote 202 for zener impedance variation with different operating currents. o 3. The reverse surge current is measured at 25 C ambient using a square wave or equivalent half-sine wave pulse 1/120 second duration superimposed on I . ZT 4. Zener voltage (V ) is measured at T = 25C (+8, -2C) and 90 seconds after application of dc current. Z L Copyright 2007 Microsemi Page 2 6-20-2007 REV E Scottsdale Division 8700 E. Thomas Rd.
