10D Series Varistor Type MYG Type MYG Varistors are made of semiconductor ceramic materials composed mainly of zinc oxide. They have non-linear resistance that changes as a function of applied voltage. It has small size, high current capacity, and high protection level. Features > > > > Wide Varistor voltage range (18V～１１０0V) Excellent non-linearity and protection level Large withstanding surge current Fast response（≤20ns） Recommended Applications > ＞> > > Protection of semiconductors Surge protection of consumer equipment Surge protection of communication, measuring or controller instrument Relay or electromagnetic Valve surge absorption Explanation of Part Numbers D Element Size 10 10mm Varistor Voltage The first two digits are Significant figures and the third one denotes number of zeros following Voltage Tolerance K:±10% Dimension Range of voltage (V) D max 18 - 68 81 - 1100 Dimensions(mm) T max L min d±0.1 13.5 3.6~5.4 13.5 4.3~9.7 25 25 0.8 0.8 D1±1.0 7.5 7.5 REV.2015.02.01 01 | www.spsemi.cn 10D Series Specification and Electrical Characteristics Part Number 10D112K 10D102K 10D911K 10D821K 10D781K 10D751K 10D681K 10D621K 10D561K 10D511K * 10D471K 10D431K 10D391K 10D361K 10D331K 10D301K * 10D271K 10D241K 10D221K 10D201K 10D181K 10D151K 10D121K 10D101K * 10D820K 10D680K 10D560K * 10D470K 10D390K 10D330K 10D270K 10D220K 10D180K Maximum Allowable Voltage Acrms (V) 680 625 550 510 485 460 420 385 350 320 300 275 250 230 210 190 175 150 140 130 115 95 75 60 50 40 35 30 25 20 17 14 11 DC (V) 895 825 745 670 640 615 560 505 460 415 385 350 320 300 275 250 225 200 180 170 150 125 100 85 65 56 45 38 31 26 22 18 14 Maximum Energy 10/100μS (J) 133.0 133.0 133.0 124.6 124.6 124.6 102.2 102.2 99.4 99.4 99.4 88.2 81.2 74.2 68.6 63.0 57.4 50.4 46.2 42.0 30.8 25.2 21.0 18.2 16.8 15.4 12.9 10.8 9.1 7.4 6.0 4.5 2.8 Withstanding Surge Current 8/20μs 1 time Rated Wattage 2times (W) (A) 2500 1250 0.4 500 250 0.05 Varistor Voltage Maximum Clamping Voltage V1mA (V) 1100(990-1210) 1000(900-1100) 910(819-1001) 820(738-902) 780(702-858) 750(675-825) 680(612-748) 620(558-682) 560(504-616) 510(459-561) 470(423-517) 430(387-473) 390(351-429) 360(324-396) 330(297-363) 300(270-330) 270(243-297) 240(216-264) 220(198-242) 200(180-220) 180(162-198) 150(135-165) 120(108-132) 100(90-110) 82(74-90) 68(61-75) 56(50-62) 47(42-52) 39(35-43) 33(30-36) 27(24-30) 22(20-24) 18(15-21) V25A (V) 1815 1650 1500 1355 1290 1240 1120 1025 920 845 775 710 650 595 550 505 455 395 360 330 300 250 200 165 135 *135 *110 *93 *77 *65 *53 *43 *38 Note：1、* Stand for commonly used models 2、Varistor voltage is measured at 0.1 mA for 05D, and at 1 mA for 07D, 10D, 14D, 20D, respectively. 3、Operating Temperature Range: －40℃～+85℃ Storage Temperature Range: －40℃～+125℃ REV.2015.02.01 02 | www.spsemi.cn
