Leadless Package For Surface Mount Technology  
Ideal For High Density Mounting  
Voltage Range 6.8 To 200 Volts  
Hermetically Sealed, Double Slug Glass Construction  
Metallurgically Bonded Construction Available as Dash One.  
Available in JAN, JTX, JTXV-1 to Mil-PRF-19500/117 (UR-1 Suffix)  
LEADLESS GLASS  
ZENER DIODE  
SURFACE MOUNT  
Maximum Ratings  
500 mW DC Power Dissipation (See Power Derating Curve In Figure 1)  
-55°C to +175°C Operating and Storage Junction Temperature  
Package Dimensions In Inches  
Application  
This surface mountable zener diode series is similar to the 1N957B thru  
1N992B 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.  
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.  
** Ordering Information:
