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:
1) Commercial: MLL957B thu MLL992B orMLL957B-1 thru MLL992B-1
2) Military: JAN, JANTX, or JANTXV 1N962BUR-1 thru 1N992BUR-1
3) Tight tolerance "C" suffix = ±2%, "D" suffix = ±1%
4) Surge is square wave or equivalent ½ sine wave pulse of 1/120 second duration.
