Dynamic resistance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 2) Valid provided that electrodes are kept at ambient temperature. 3) Tested with pulses tp = 20 ms. 4) The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current IZT. www.msksemi.com ZM4727-ZM4761 Semiconductor Compiance   Power Dissipation vs Ambient Temperature Power Dissipation: Ptot (mW) 1200 1000 800 600 400 200 0 0 25 50 75 100 125 150 175 Ambient Temperature: Ta ( C) O www.msksemi.com ZM4727-ZM4761 Semiconductor Compiance Attention ■ Any and all MSKSEMI Semiconductor products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
