Longer or shorter test times will have a correspond- ing 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. #Ratings are based on free air. Ta is 25C. For use at 1.5 watts see derating curve. Figures shown are for a peak sinusoidal surge current of 8.3 ms duration using 60 cycle AC. The 8.3 ms square pulse rating is 71% of the vatue shown. UNITRODE CORPORATION 5 FORBES ROAD LEXINGTON, MA 02173 TEL. (617) 861-6540 TWX (710) 326-6509 TELEX 95-1064 514 PRINTED IN U.S.A.
