n ot e 1 : vz: toleranc e +/-5% 2: the zener impedance is derived from the 60 hz ac voltage, which results when an ac current having a n rms value equal to 10% of the dc zener current(i zt or i zk ) is superimposed on i zt or i zk . zener impedance is measured at two points to insure a sha rp knee on the breakdown curve and eliminate unstable units. 3: the reverse surge current is measured at 25 o c ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second duration superimposed on i zt . 4: voltage measurements tobe performed 90 seconds a fter application of dc current. m c c 5: rohs compliant already and pb-free sticker on ree l , box & carto n indicated rohs compliant . mcc zene r test s u r g e m ax imum part numbe r voltag e curren t regu l ato r device urrent curren t marking v z @i zt i zt z zt @i zt z z k @ i z k i z k i r @ v r v r i r i volt s m a ohm s ohm s m a u a volt s ma ma z m 1n472 9a w 3. 6 6 9 1 0 40 01 1 0 0 1 126 0 2 5 2 729 1n473 0a w 3. 9 6 4 9 40 0 1 5 0 1 119 0 23 4 730 1n473 1a w 4. 3 5 8 9 40 0 1 1 0 1 107 0 21 7 731 1n473 2 a w 4. 7 5 3 8 50 0 1 1 0 1 9 7 0 19 3 732 1n473 3 a w 5. 1 4 9 7 55 0 1 1 0 1 8 9 0 17 8 733 1n473 4 a w 5. 6 4 5 5 60 0 1 1 0 2 8 1 0 16 2 734 1n473 5 a w 6. 2 4 1 2 70 0 1 1 0 3 7 3 0 14 6 735 1n473 6a w 6. 8 3 7 3. 5 70 0 1 1 0 4 660 133 736 1 n 4 73 7 a w 7 . 5 3 4 4 70 0 0 . 5 1 0 5 60 5 12 1 737 1n4738 a w 8. 2 3 1 4. 5 70 0 0. 5 1 0 6 550 110 738 1 n 4 73 9 a w 9 . 1 2 8 5 70 0 0 . 5 1 0 7 50 0 10 0 739 1n474 0 a w 1 0 2 5 7 70 0 0.2 5 1 0 7 . 6 45 4 9 1 740 1 n 4 74 1 a w 1 1 2 3 8 70 0 0.2 5 5 8. 4 41 4 8 3 741 1 n 4 74 2 a w 1 2 2 1 9 70 0 0.2 5 5 9. 1 38 0 7 6 742 1 n 4 74 3 a w 1 3 1 9 1 0 70 0 0.2 5 5 9. 9 34 4 6 9 743 1n474 4 a w 1 5 1 7 1 4 7 0 0 0.2 55 11. 4 3 0 4 6 1 744 1 n 4 74 5 a w 1 6 15. 5 1 6 70 0 0.2 55 12. 2 28 5 5 7 745 1n474 6 a w 1 8 1 4 2 0 7 5 0 0.2 55 13. 7 2 5 0 5 0 746 1 n 4 74 7 a w 2 0 12. 5 2 2 75 0 0.2 55 15. 2 22 5 4 5 747 1 n 4 74 8 a w 2 2 11. 5 2 3 75 0 0.2 55 16. 7 20 5 4 1 748 1 n 4 74 9 a w 2 4 10. 5 2 5 75 0 0.2 55 18. 2 19 0 3 8 749 1 n 4 75 0 a w 2 7 9. 5 3 5 7 5 0 0.2 55 20. 6 17 0 34 750 1 n 4 75 1 a w 3 0 8. 5 4 0 100 0 0.2 55 22. 8 1 5 0 3 0 751 1 n 4 75 2 a w 3 3 7. 5 4 5 100 0 0.2 55 25. 1 1 3 5 2 7 752 1 n 4 75 3 a w 3 6 7 5 0 100 0 0.2 55 27. 4 12 5 2 5 753 1 n 4 75 4 a w 3 9 6. 5 6 0 100 0 0.2 55 29. 7 1 1 5 2 3 754 1 n 4 75 5 a w 4 3 6 7 0 150 0 0.2 55 32. 7 11 0 2 2 755 1n4756 a w 4 7 5. 5 8 0 150 0 0.2 55 35. 8 95 19 756 1 n 4 75 7 a w 5 1 5 9 5 150 0 0.2 55 38. 8 9 0 1 8 757 1 n 4 75 8 a w 5 6 4. 5 11 0 200 0 0.2 55 42. 6 8 0 1 6 758 1 n 4 75 9 a w 6 2 4 12 5 200 0 0 . 2 55 47. 1 7 0 1 4 759 1 n 4 76 0 a w 6 8 3. 7 15 0 200 0 0.2 55 51. 7 6 5 1 3 760 1 n 4 76 1 a w 7 5 3. 3 17 5 200 0 0.2 5 5 5 6 6 0 1 2 761 leakage current maximum reverse maximum dynamic impedance electrical characteristics (t a = 25c unless otherwise noted). maximum v f = 1.2v at i f = 200ma 1n47 2 9a w thru 1n47 6 1 aw www. mccsemi .com 2 of 4 tm micro commercial components m c c revision : a 20 1 3 / 0 1 / 0 2 downloaded from: http:///
