* JEDEC Registered Data
NOTE 1: Standard tolerance on JEDEC 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
I
ZT
, a 60 cps, rms ac current equal to 10% I
ZT
(2mA ac). See MicroNote 202 for
typical zener Impedance variation with different operating currents.
NOTE 4: Allowance has been made for the increase in
V
Z
due to Z
Z
and for the increase in junction temperature as the unit approaches
thermal equilibrium at the power dissipation of 400 mW.
