NOTE 5 - MAXIMUM REGULATOR CURRENT(Iz, ) The maximum current shown is based on the maximum voltage of a 5.0% type unit, therefore, it applies only to the B suf- fix device. The actual Iz, for any device may not exceed the value of 400 milliwatts divided by the actual Vz of the device. NOTE 6 - MAXIMUM REGULATION FACTOR( AV_) AV; is the maximum difference between Vz at Iz; and Vz at lz, measured with the device junction in thermal equilibrium.
