07D 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～ 0V) 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 07 07mm Varistor Voltage The first two digits are Significant figures and the third one denotes number of zeros following Voltage Tolerance K:±10% Dimension Element 07 07mm Size L:± K:± REV.2015.02.01 Voltage Tolerance 15% 10% Range of voltage (V) D max 18 - 68 82 - 820 9.0 9.0 Dimensions(mm) T max L min d±0.1 3.5~6.0 4.2~6.5 25 20 0.6 0.6 D1±1.0 5.0 5.0 01 | www.spsemi.cn 07D Series Specification and Electrical Characteristics Part Number Maximum Allowable Voltage 07D821K 07D781K 07D751K 07D681K 07D621K 07D561K 07D511K * 07D471K 07D431K 07D391K 07D361K 07D331K 07D301K * 07D271K 07D241K 07D221K 07D201K 07D181K 07D151K 07D121K 07D101K * 07D820K 07D680K 07D560K * 07D470K 07D390K 07D330K 07D270K 07D220K 07D180K Acrms (V) 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) 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) 67.2 67.2 67.2 61.6 61.6 56.0 56.0 56.0 50.4 46.2 42.0 37.8 35.0 32.2 28.0 28.0 25.2 18.2 16.8 14.0 11.6 9.8 7.3 6.2 5.0 4.2 3.5 2.8 2.4 2.1 Withstanding Surge Current 8/20μs 1 time Rated Varistor Voltage Wattage 2times (W) (A) 1200 600 0.25 250 125 0.02 V1mA (V) 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) Maximum Clamping Voltage V5A (V) 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℃ 02 | www.spsemi.cn REV.2015.02.01
