05D 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～７５0V) 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 05 05mm 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 - 750 REV.2015.02.01 7.5 7.5 Dimensions(mm) T max L min d±0.1 3.5 4.1~6.2 25 20 0.6 0.6 D1±1.0 5.0 5.0 01 | www.spsemi.cn 05D Series Specification and Electrical Characteristics Part Number 05D751K 05D681K 05D621K 05D561K 05D511K * 05D471K 05D431K 05D391K 05D361K 05D331K 05D301K * 05D271K 05D241K 05D221K 05D201K 05D181K 05D151K 05D121K 05D101K * 05D820K 05D680K 05D560K * 05D470K 05D390K 05D330K 05D270K 05D220K 05D180K Maximum Allowable Voltage Maximum Energy Acrms DC 10/100μS (V) 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 (V) 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 (J) 22.4 21.0 21.0 19.6 19.6 18.2 16.8 15.4 14.0 14.0 11.8 10.2 9.9 8.8 7.7 5.6 4.2 4.2 2.8 2.8 1.8 1.5 1.4 1.1 0.8 0.7 0.6 0.4 Withstanding Surge Current 8/20μs 1 time Rated Wattage 2times (A) (W) 400 200 0.1 100 50 0.01 Varistor Voltage Maximum Clamping Voltage V0.1mA V5A (V) 750(675-825) 680(612-748) 620(558-682) 560(504-616) 510(459-561) 470(423-517) 430(387-473) 390(351-249) 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) (V) 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
