DESCRIPTION

APPEARANCE

This surface mountable 1 watt Zener diode series is electrically equivalent to

the 1N4728A thru 1N4764A registration in the DO-41 equivalent package

except that it meets the JEDEC surface mount outline DO-213AB and also

includes enhanced internal contact design. 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).

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 (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.

NOTE 3: The reverse surge current is measured at 25^oC ambient using a ½ 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-1 thru MLL4764A-1 series. This alternate name may

still be used.
