Application

This surface mountable zener diode series is similar to the 1N746 thru

1N759 in the DO-35 equivalent package except that it meets the new

JEDEC surface mount outline DO-213AA. It is an ideal selection for

applications of high density and low parasitic requirements. Due to its

glass hermetic qualities, it may also be considered for high reliability

applications.
