DESCRIPTION APPEARANCE
This surface mountable 1.5 W Zener diode series in the JEDEC DO-213AB
package is similar in electrical features to the JEDEC registered 1N5913B
thru 1N5956B axial-leaded package for 3.3 to 200 V. It is an ideal selection
for applications of high density and low parasitic requirements. Due to its
glass hermetic qualities and metallurgically enhanced internal contacts, it
may also be used for high reliability applications when required by a source
control drawing (SCD) or screening in accordance with MIL-PRF-19500 as
described in Features below. Zener voltage tolerance options are identified
by part number suffix including tight-tolerance. A variety of other Zener
product offerings and packages are available by Microsemi to meet higher
or lower power and test current applications.

TEC Maintained at 30oC, VF = 1.2V max @ IF = 200 mA (all types).
NOTE 1: No suffix indicates a +/-20% tolerance on nominal VZ. The suffix A denotes +/-10%, the standard suffix B denotes +/-5%, C denotes +/-2%, and
D denotes +/-1% tolerance.
NOTE 2: Zener voltage (VZ) is measured at end cap temperatures TEC = 30oC. Voltage measurement to be performed 90 seconds after application of dc
current.
NOTE 3: The zener impedance is derived from the 60 Hz 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.
NOTE 4: This product series has also been previously identified as the MLL5913B thru MLL5956B series that included the enhanced metallurgical bond.
This alternate name may still be used.
