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 leads at a distance of 8 mm from case 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. ® Dated : 03/08/2011 Rev: 01 0 10 20 20 30 40 50 60 70 8 10 80 9 90 IN4764 7 IN4738 IN4737 IN4741 IN4740 IN4739 30 IN4763 6 IN4762 5 IN4761 40 IN4736 50 IN4760 30 4 IN4758 0 IN4757 50 3 IN4755 2 IN4735 IN4734 IN4733 IN4731 IN4732 IN4730 IN47 29 60 IN4759 Iz IN4727 IN4728 70 IN4750 IN4751 IN4752 80 IN4756 40 1 IN4746 IN4747 IN4748 IN4749 90 IN4753 IN4754 mA IN4743 IN4744 0 IN4745 Iz IN4742 1N4727A...1N4761A Tj =constant(pulsed) Breakdowm characteristics mA 100 IN...
