(or MLL5913B thru MLL5956B)

METALLURGICALLY BONDED GLASS

SURFACE MOUNT 1.5 WATT ZENERS

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

DO-213AB

or lower power and test current applications.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

* T_ECMaintained at 30^oC, V_F= 1.2V max @ I_F= 200 mA (all types).

NOTE 1: No suffix indicates a +/-20% tolerance on nominal V_Z. The suffix A denotes +/-10%, the standard suffix B denotes +/-5%, C denotes +/-2%, and

D denotes +/-1% tolerance.

NOTE 2: Zener voltage (V_Z) is measured at end cap temperatures T_EC= 30^oC. 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 (I_ZTor I_ZK) is superimposed on I_ZTor I_ZK

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.
