* 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

typical zener Impedance variation with different operating currents.

NOTE 4: Allowance has been made for the increase in

thermal equilibrium at the power dissipation of 400 mW.
