Longer or shorter test times will have a corres- ponding effect on the measured value due to heating effects. . Zener impedance is derived from the 60 cycle AC Voltage created when AC current with RMS value of 10% of DC Zener test. current is superim- posed on the test current. ** ABV is obtained by measuring the voltage change when the test current is changed from 10% to 50% of Iz max under DC conditions. During this measurement the leads are heat sunk .375 inch from the body and maintained at 25C. $ Ratings shown are for peak sinusoidal surge current of 8.3 ms duration, non-repetitive. The 8.3 ms square pulse rating is 71% of the value shown. Rating exceeds JEDEC Registered Specification. UNITRODE CORPORATION 5 FORBES ROAD LEXINGTON, MA 02173 + TEL.
