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.

FEATURES
APPLICATIONS / BENEFITS
Electrically similar to the JEDEC registered 1N5913B
thru 1N5956B zener series
Zener voltages available 3.3V to 200V
Options for screening in accordance with MIL-PRF-
19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers, e.g. MX1N5913BUR-1,
MV1N5923CUR-1, MSP1N5952DUR-1, etc.
Surface mount equivalents also available as
SMBJ5913B to SMBJ5956B, SMBG5913B to
SMBG5956B, or SMAJ5913B to SMAJ5956B (see
