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 IZT at 60 Hz rms ac current equal to 10% IZT (2 mA ac).
Note 3 Allowance has been made for the increase in VZ due to ZZ and for the increase in junction temperature as the unit approaches thermal equilibrium at the power dissipation at 500 mW.
