SURFACE MOUNT 1.0 W

GLASS ZENER DIODES

DESCRIPTION

APPEARANCE

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).

DO-213AB
