SCOTTSDALE DIVISION
1N4728UR thru 1N4764AUR
(or MLL4728A thru MLL4764A)
SURFACE MOUNT 1.0 W
GLASS ZENER DIODES
DESCRIPTION
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. 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).

APPEARANCE
DO-213AB
FEATURES
• Electrically similar to the JEDEC registered 1N4728
thru 1N4764 zener series
• Zener voltages available 3.3V to 100V
• Standard voltage tolerances are +/- 5% with “A” suffix
and 10 % with no suffix identification
• Tight tolerances available in plus or minus 2% or 1%
with C or D suffix respectively
• 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.
• Surface mount equivalents also available as
SMAJ4728A to SMAJ4764A and SMAJ4728A to
SMAJ4764A
• Plastic body axial-leaded Zener equivalents are also
available as 1N4728A to 1N4764A
