Package Dimensions In Inches  
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.

Finish: All external surfaces are corrosion  
resistant, readily solderable.  
Note 1 Voltage measurements to be performed 20 seconds after application of dc  
test current.  
Polarity: Banded end is cathode.  
Note 2 Zener impedance derived by superimposing on IZT at 60 Hz rms ac current  
equal to 10% IZT (2 mA ac).  
Thermal Resistance: 100°C/Watt Maximum  
junction to end caps for "-1" construction and  
150°C/W maximum junction to end caps for  
commercial.  
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.
