Zener im pedance is measured at tw o points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 2) Valid provided that electrodes at a distance of 10mm from case are kept at ambient temperature 3) M easured under thermal equil ibri um and DC test conditi ons. Admissible power dissipation versus ambient temperature (Valid provided that leads at a distance of 10mm from case are kept at ambient temperature) W 1.0 1N4728...1N4764 Ptot 0.8 0.6 0.4 0.2 0 0 100 Tam b 200 C
