Lead Mounted: See lead temperature derating curve. Temperature Range: Operating and storage -65C to 175C. * Specify 20% tolerance by changing the second numeral of type number from 8 to 9 (UZ7809 becomes UZ7909) or from 2 to 3 (UZ7210 becomes UZ7310). Specify leaded version by adding an L suffix (UZ7809 becomes UZ7809L). t+ All zener voltages are measured with an automated test set using a 35 msec test time. Longer or shorter test times will have a corresponding effect on the measured value due to heating effects. Zener impedance is derived from the 60-cycie voltage created when AC current with RMS value of 10% of DC zener test current is superimposed on the test current. %* Ratings Based on 100C Case temperature; for leaded devices multiply by 0.6. { Figures shown are for a peak sinusoidal surge current of 8.3ms duration, non-repetitive. The 8.3ms square pulse rating is 71% of the value shown.
