* JEDEC Registered Data
NOTE 1: Standard tolerance on types shown is +/- 10%. Suffix letter A denotes +/- 5% tolerance; suffix
letter C denotes +/- 2%; and suffix letter D denotes +/- 1% tolerance.
NOTE 2: Voltage measurements to be performed 20 seconds after application of dc test current.
NOTE 3: Zener impedance derived by superimposing on
IZT, a 60 cps, rms ac current equal to 10% IZT (2 mA ac). See MicroNote 202 for
typical zener Impedance variation with different operating currents.
NOTE 4: 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 of 400 mW.
NOTE 5: These may be ordered as either 1N4370UR-1 thru 1N4372AUR-1 and 1N746UR-1 thru 1N758AUR-1, or as MLL4370-1 thru
MLL4372A-1 and MLL746-1 thru MLL758A-1. For military types, use the 1NxxxUR-1 format and also include JAN, JANTX, or JANTXV
prefix for desired screening level, e.g. JANTX1N4370UR-1, JANTXV1N746AUR-1, JANTXV1N758UR-1, etc.
