Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 2) Valid provided that leads at a distance of 10 mm from case are kept at ambient temperature. 3) Measured under thermal equilibrium and DC test conditions. 209ITT SEMICOND/ INTERMETALL SOE 1N4729 ... 1N4764 D MB 4682731 0002929 44e MISTI Rot 0.8 06 04 0.2 Admissible power dissipation versus ambient temperature Valid provided that leads are kept at ambient temperature at a distance of 10 mm from case. 1N4729... 0 100 200C aaa Tamb 210
