It is an ideal selection for applications of high density and low parasitic requirements for voltage regulation. Standard voltage tolerance is +/- 5% with tighter tolerances available down to 1%. With its glass hermetic qualities, it may also be used for high reliability applications when required by a source control drawing (SCD).

Also available with suffix C for +/-2%, and D for +/-1%, while the absence of a suffix letter denotes +/- 10% tolerance. NOTE 2: The Zener impedance is derived from the 60Hz ac voltage, which 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 breakdown curve and ZT ZK ZT ZK eliminate unstable units. o NOTE 3: The reverse surge current is measured at 25 C ambient using a square wave or equivalent sine wave pulse 1/120 second duration superimposed on I . ZT NOTE 4: Voltage measurements to be performed 90 seconds after application of dc current. NOTE 5: This product series has also been previously identified as the MLL4728A thru MLL4764A series. This alternate name may still be used. Copyright 2005 Microsemi Page 2 10-18-2005 REV D Scottsdale Division 8700 E. Thomas Rd.
