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.

Note 1 Voltage measurements to be performed 20 seconds after application of dc
test current.
Note 2 Zener impedance derived by superimposing on I

at 60 Hz rms ac current
equal to 10% I

(2 mA ac).
Note 3 Allowance has been made for the increase in V
Z
due to Z
Z
and for the
increase in junction temperature as the unit approaches thermal equilibrium at the
power dissipation at 500 mW.
