note 1: the jedec type number shown with an a suffix have a 5% tolerance. 2: the zener impedance is derived from the 60 hz ac voltage, which results when an ac current having an 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 sharp knee on the breakdown curve and eliminate unstable units. 3: the reve rse 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 after application of dc current. 5: rohs compliant already and pb-free sticker on reel , box & carto n indicated rohs compliant . electrical characteristics (t a = 25? unless otherwise noted). maximum v f = 1.2v at i f = 200ma 1n4736ap thru 1n4764ap www. mccsemi .com 2 of 4 r evision: c 2 017/01/01 maximum dc zen er c urrent maximum surge current vz @ izt izt zzt @ izt zzk @ izk izk izm irm (v) (ma) ( ) ( ) (ma) (a) (v) (ma) (mapk) 1n4736ap 6.8 37.0 3.5 700 1 .0 10 4 .0 133 660 1n4737ap 7.5 34.0 4.0 700 0 .5 10 5 .0 121 605 1n4738ap 8.2 31.0 4.5 700 0 .5 10 6 .0 110 550 1n4739ap 9.1 28.0 5.0 700 0 .5 10 7 .0 100 500 1n4740ap 10 25 .0 7.0 700 0 . 25 10 7.6 91 454 1n4741ap 11 23 .0 8.0 700 0 . 25 5.0 8.4 83 414 1n4742ap 12 21 .0 9.0 700 0 . 25 5.0 9.1 76 380 1n4743ap 13 19.0 10 700 0.25 5.0 9.9 69 344 1n4744ap 15 17 .0 14 700 0 . 25 5.0 11.4 61 305 1n4745ap 16 15 .5 16 700 0 . 25 5.0 12.2 57 285 1n4746ap 18 14 .0 20 750 0 . 25 5.0 13.7 50 250 1n4747ap 20 12 .5 22 750 0 . 25 5.0 15.2 45 225 1n4748ap 22 11 .5 23 750 0 . 25 5.0 16.7 41 205 1N4749AP 24 10 .5 25 750 0 . 25 5.0 18.2 38 190 1n4750ap 27 9 .5 35 750 0 . 25 5.0 20.6 34 170 1n4751ap 30 8 .5 40 1000 0 . 25 5.0 22.8 30 150 1n4752ap 33 7 .5 45 1000 0 . 25 5.0 25.1 27 135 1n4753ap 36 7 .0 50 1000 0 . 25 5.0 27.4 25 125 1n4754ap 39 6 .5 60 1000 0 . 25 5.0 29.7 23 115 1n4755ap 43 6 .0 70 1500 0 . 25 5.0 32.7 22 110 1n4756ap 47 5 .5 80 1500 0 . 25 5.0 35.8 19 95 1n4757ap 51 5 .0 95 1500 0 . 25 5.0 38.8 18 90 1n4758ap 56 4 .5 110 2000 0 . 25 5.0 42.6 16 80 1n4759ap 62 4 .0 125 2000 0 . 25 5.0 47.1 14 70 1n4760ap 68 3 .7 150 2000 0 . 25 5.0 51.7 13 65 1n4761ap 75 3 .3 175 2000 0 . 25 5.0 56.0 12 60 1n4762ap 82 3 .0 200 3000 0 . 25 5.0 62.2 11 55 1n4763ap 91 2 .8 250 3000 0 . 25 5.0 69.2 10 50 1n4764ap 100 2 .5 350 3000 0 . 25 5.0 76.0 9.0 45 mcc part number nominal zener voltage maximum zener impedance maximum reverse leakage current ir @ vr micro commercial components m c c r
