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 vo ltage divided by the ac current with rms va lue of 10% of dc zener test current super imposed on the test current. 3 / ratings based on maximum zener voltage of individual units (leaded units). 4 / figures shown are for a peak sinu soidal surge current of 8.3 msec duration, non-repetitive. the 8.3 msec square pulse r ating is 71% of the value shown. 5 / ssdi standard marking consists of a contrasting color cathode dot or band. part number information is included on packa ging labels. 6 / for ordering information, price, and availability- contact factory. 7 / screening based on mil-prf-19500. screening flows available on request. 8 / voltages are shown for 5% tolerance devices. 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 szn4460 thru szn4496 series and szn6485 thru szn6491 series electrical characteristics @ 25c nominal zener voltage (note 1) zener test current maximum zener impedance (note 2) maximum knee impedance maximum reverse leakage current maximum continuous current (note 3) maximum surge current (note 4) part number vz @ izt izt zz @ izt zzk @ izk ir @ vr vr (note 8) izm izsm volt ma ohms ohms ma a volts ma amps szn6485 szn6486 szn6487 szn6488 szn6489 szn6490 szn6491 3.3 3.6 3.9 4.3 4.7 5.1 5.6 76 69 64 58 53 49 45 10 10 9 9 8 7 5 400 400 400 400 500 500 600 1.0 1.0 1.0 1.0 1.0 1.0 1.0 50 50 35 5.0 4.0 1.0 0.5 1.0 1.0 1.0 1.0 1.0 1.0 2.0 433 397 366 332 304 280 255 4.2 3.9 3.6 3.3 3.0 2.7 2.5 szn4460 szn4461 szn4462 szn4463 szn4464 6.2 6.8 7.5 8.2 9.1 40.0 37.0 34.0 31.0 28.0 4 2.5 2.5 3 4 200 200 400 400 500 1.0 1.0 .5 .5 .5 10.0 5.0 1.0 .50 .30 3.72 4.08 4.50 4.92 5.46 230 210 191 174 157 2.3 2.1 1.9 1.7 1.6 szn4465 szn4466 szn4467 szn4468 szn4469 10.0 11.0 12.0 13.0 15.0 25.0 23.0 21.0 19.0 17.0 5 6 7 8 9 500 550 550 550 600 .25 .25 .25 .25 .25 .30 .30 .20 .05 .05 8.00 8.80 9.60 10.40 12.00 143 130 119 110 95 1.4 1.3 1.2 1.1 .95 szn4470 szn4471 szn4472 szn4473 szn4474 16.0 18.0 20.0 22.0 24.0 15.5 14.0 12.5 11.5 10.5 10 11 12 14 16 600 650 650 650 700 25 .25 .25 .25 .25 .05 .05 .05 .05 .05 12.80 14.40 16.00 17.60 19.20 90 79 71 65 60 .90 .79 .71 .65 .60 szn4475 szn4476 szn4477 szn4478 szn4479 27.0 30.0 33.0 36.0 39.0 9.5 8.5 7.5 7.0 6.5 18 20 25 27 30 700 750 800 850 900 .25 .25 .25 .25 .25 .05 .05 .05 .05 .05 21.60 24.00 26.40 28.80 31.2 53 48 43 40 37 .53 .48 .43 .40 .37 szn4480 szn4481 szn4482 szn4483 szn4484 43.0 47.0 51.0 56.0 62.0 6.0 5.5 5.0 4.5 4.0 40 50 60 70 80 950 1000 1100 1300 1500 .25 .25 .25 .25 .25 .05 .05 .05 .25 .25 34.4 37.6 40.8 44.8 49.6 33 30 28 26 23 .33 .30 .28 .26 .23 szn4485 szn4486 szn4487 szn4488 szn4489 68.0 75.0 82.0 91.0 100.0 3.7 3.3 3.0 2.8 2.5 100 130 160 200 250 1700 2000 2500 3000 3100 .25 .25 .25 .25 .25 .25 .25 .25 .25 .25 54.4 60.4 65.6 72.8 80.8 21 19 17 16 14 .21 .19 .17 .16 .14 szn4490 szn4491 szn4492 SZN4493 szn4494 110.0 120.0 130.0 150.0 160.0 2.0 2.0 1.9 1.7 1.6 300 400 500 700 1000 4000 4500 5000 6000 6500 .25 .25 .25 .25 .25 .25 .25 .25 .25 .25 88.0 96.0 104.0 120.0 128.0 13 12 11 9.5 8.9 .13 .12 .11 .095 .089 szn4495 szn4496 180.0 200.0 1.4 1.2 1300 1500 7000 8000 .25 .25 25 .25 144.0 160.0 7.9 7.2 .079 .072 note: all specifications are subject to change without notification. scd's for these devices should be re viewed by ssdi prior to release. data sheet #: z00008g doc http://www..net/ datasheet pdf - http://www..net/
