SCOTTSDALE DIVISION
METALLURGICALLY BONDED GLASS
SURFACE MOUNT 1.0 W ZENERS
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 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).
