• Voltage Range 2.4 To 12 Volts
• Hermetically Sealed, Double Slug Glass Construction
• Metallurgically Bonded Construction Available as Dash One.
• Available in JAN, JTX, JTXV-1 To Mil-PRF-19500/127 (UR-1 Suffix)
Maximum Ratings
500 mW DC Power Dissipation (See Power Derating Curve In Figure 1)
-55°C to +175°C Operating and Storage Junction Temperature
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.
