note 1: vz: tolerance +/-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 re el , box & carto n indicated rohs compliant . mcc zene r test s u r g e maximum part numbervoltagecurrent regulator device urrent current marking v z @i zt i zt z zt @i zt z zk @i zk i zk i r @v r v r i r i voltsmaohmsohmsmauavoltsma ma zm 1n4729 aw3.66910400110011260 252 729 1n4730 aw3.964940015011190 234 730 1n4731 aw4.358940011011070 217 731 1n4732 aw4.75385001101970 193 732 1n4733 aw5.14975501101890 178 733 1n4734 aw5.64556001102810 162 734 1n4735 aw6.24127001103730 146 735 1n473 6aw6.8373.57001104660 133 736 1n4737 aw7.53447000.5105605 121 737 1n4738 aw8.2314.57000.5106550 110 738 1n4739 aw9.12857000.5107500 100 739 1n4740 aw102577000.25107.6454 91 740 1n4741 aw112387000.2558.4414 83 741 1n4742 aw122197000.2559.1380 76 742 1n4743 aw1319107000.2559.9344 69 743 1n4744 aw1517147000.25511.4304 61 744 1n4745 aw1615.5167000.25512.2285 57 745 1n4746 aw1814207500.25513.7250 50 746 1n4747 aw2012.5227500.25515.2225 45 747 1n4748 aw2211.5237500.25516.7205 41 748 1n4749 aw2410.5257500.25518.2190 38 749 1n4750 aw279.5357500.25520.6170 34 750 1n4751 aw308.54010000.25522.8150 30 751 1n4752 aw337.54510000.25525.1135 27 752 1n4753 aw3675010000.25527.4125 25 753 1n4754 aw396.56010000.25529.7115 23 754 1n4755 aw4367015000.25532.7110 22 755 1n4756 aw475.58015000.25535.895 19 756 1n4757 aw5159515000.25538.890 18 757 1n4758 aw564.511020000.25542.680 16 758 1n4759 aw62412520000.25547.170 14 759 1n4760 aw683.715020000.25551.765 13 760 1n4761 aw753.317520000.2555660 12 761 leakage current maximum reverse maximum dynamic impedance electrical characteristics (t a = 25c unless otherwise noted). maximum v f = 1.2v at i f = 200ma 1n472 9 aw thru 1n4761aw www. mccsemi .com 2 of 4 tm micro commercial components m c c revision: a 201 3/0 1 /02
