NOTE 1: The type numbers shown with an “A” suffix have a +/-5% tolerance on the nominal Zener voltage. It is also available with suffix
“C” for +/-2%, and “D” for +/-1%. 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 (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.
NOTE 3: The reverse surge current is measured at 25
oC ambient using a square wave or equivalent sine wave pulse 1/120 second
duration superimposed on IZT.
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-1 thru MLL4764A-1 series. This alternate name may
still be used.
