notes: 1/ all zener voltages are measured with an automated test set using a 35 msec test time. longer or shorter test time will have a corresponding effect on the measured value due to heating effects. 2/ zener impedance is derived from the ac voltage divided by the ac current with rms value of 10% of dc zener test current s uperimposed on the test current. 3/ ssdi standard marking consists of a contrasting color cathode dot or band. part number information is included on pack aging labels. 4/ for ordering information, price, operating curves, and availability- contact factory. 5/ screening based on mil-prf-19500. screening flows available on request. 6/ suffix ?sm? for round tab surface mount and ?sms? for square tab surface mount. 7/ temperature range of coefficient is -55 c to +150 c. 8/ figures shown are for a peak sinusoidal surge current of 8.3 msec duration, non-repetitive. the 8.3 msec square wave pu lse rating is 71% of the value shown. solid state devices, inc. 14701 firestone blvd * la mirada, ca 90638 phone: (562) 404-4474 * fax: (562) 404-1773 ssdi@ssdi-power.com * www.ssdi-power.com sz1a3.3 thru sz1a100 electrical characteristics @ 25c (unless otherwise specified) maximum continuous current part number (note 6) nominal zener voltage (note 1) zener test current maximum zener impedance (note 2) maximum reverse leakage current typical range of temperature coefficient (note 7) axial (__) surface mount (sm) & ( sms ) maximum surge current (note 8) voltage tolerance vz @ izt izt zz @ izt zzk @ izk = 10%izt ir @ vr vr 10% (a suffix) vr 5% (b suffix) tc @ izt izm izm izsm 10% 5% volts ma ohms a volts mv/oc ma ma sz1a3.3 sz1a3.6 sz1a3.9 sz1a4.3 sz1a4.7 sz1b3.3 sz1b3.6 sz1b3.9 sz1b4.3 sz1b4.7 3.3 3.6 3.9 4.3 4.7 76 69 64 58 53 10 10 9.0 9.0 8.0 400 400 400 400 500 100 100 50 10 10 0.95 0.95 0.95 0.95 0.95 1.0 1.0 1.0 1.0 1.0 -3 to 0 -3 to 0 -3 to 0 -3 to 0 -2 to 1 276 252 238 213 194 414 378 357 319.5 291 1380 1260 1190 1070 970 sz1a5.1 sz1a5.6 sz1a6.2 sz1a6.8 sz1a7.5 sz1b5.1 sz1b5.6 sz1b6.2 sz1b6.8 sz1b7.5 5.1 5.6 6.2 6.8 7.5 49 45 41 37 34 7.0 5.0 2.0 1.5 3.5 550 600 700 700 700 10 10 10 10 10 0.95 1.90 2.90 2.90 2.90 1.0 2.0 3.0 3.0 3.0 0 to 2 1 to 3 2 to 4 2.5 to 4.5 3 to 5 178 162 146 133 121 267 243 219 199.5 181.5 890 810 730 660 605 sz1a8.2 sz1a9.1 sz1a10 sz1a11 sz1a12 sz1b8.2 sz1b9.1 sz1b10 sz1b11 sz1b12 8.2 9.1 10 11 12 31 28 25 23 21 4.0 4.5 5.0 7.0 8.0 700 700 700 700 700 10 10 10 7.5 5.0 5.0 5.3 5.9 6.6 7.2 5.2 5.7 6.2 6.9 7.6 4 to 5.5 5 to 6.3 5.8 to 7.0 6.8 to 8 7.9 to 9.0 140 125 115 105 95 210 187.5 172.5 157.5 142.5 550 500 454 414 380 sz1a13 sz1a15 sz1a16 sz1a18 sz1a20 sz1b13 sz1b15 sz1b16 sz1b18 sz1b20 13 15 16 18 20 19 17 15.5 14.0 12.5 9.0 10 14 16 20 700 700 700 750 750 5.0 2.0 1.0 1.0 1.0 8.0 8.6 9.4 10.8 11.6 8.4 9.1 9.9 11.4 12.2 10 to 13 11 to 14 12 to 15 14 to 17 16 to 19 85 80 74 63 60 127.5 120 111 94.5 90 344 304 285 250 225 sz1a22 sz1a24 sz1a27 sz1a30 SZ1A33 sz1b22 sz1b24 sz1b27 sz1b30 sz1b33 22 24 27 30 33 11.5 10.5 9.5 8.5 7.5 22 23 25 35 40 750 750 750 1000 1000 0.5 0.5 0.5 0.5 0.5 13.0 14.4 15.9 17.3 19.8 13.7 15.2 16.7 18.2 20.6 17 to 20 19 to 22 21 to 24 24 to 28 28 to 32 52 47 43 40 34 78 70.5 64.5 60 51 205 190 170 150 135 sz1a36 sz1a39 sz1a43 sz1a47 sz1a51 sz1b36 sz1b39 sz1b43 sz1b47 sz1b51 36 39 43 47 51 7.0 6.5 6.0 5.5 5.0 45 50 60 70 80 1000 1000 1500 1500 1500 0.5 0.5 0.5 0.5 0.5 21.8 24.1 26.4 28.7 30.7 22.8 25.1 27.4 29.7 32.7 30 to 35 32 to 37 35 to 40 40 to 45 44 to 50 31 28 26 23 21 46.5 42 39 34.5 31.5 125 115 110 95 90 sz1a56 sz1a62 sz1a68 sz1a75 sz1a82 sz1b56 sz1b62 sz1b68 sz1b75 sz1b82 56 62 68 75 82 4.5 4.0 3.7 3.3 3.0 95 110 125 150 175 2000 2000 2000 2000 3000 0.5 0.5 0.5 0.5 0.5 33.8 36.8 40.6 45.1 48.7 35.8 38.8 42.6 47.1 51.7 48 to 54 53 to 60 60 to 68 65 to 74 70 to 80 19 18 17 15 14 28.5 27 25.5 22.5 21 80 70 65 60 55 sz1a91 sz1a100 sz1b91 sz1b100 91 100 2.8 2.5 200 250 3000 3000 0.5 0.5 53.0 59.2 56.0 62.2 80 to 91 90 to 100 12 11 18 16.5 50 45 note: all specifications are subject to change without notification. scd's for these devices should be reviewed by ssdi prior to release. data sheet #: z00003g doc
