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 electrodes at a distance of 10mm from case are kept at ambient temperature (3) Measured under thermal equilibrium and DC test conditions www.vishay.com 2 Document Number 88304 18-Apr-02 1N4728 thru 1N4764 Vishay Semiconductors formerly General Semiconductor Ratings and Characteristic Curves (TA = 25C unless otherwise noted) 1N4728 ... 1N4764 Document Number 88304 18-Apr-02 www.vishay.com 3 |
