* 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

IZT, a 60 cps, rms ac current equal to 10% IZT (2mA 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.
