25D 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 (200V～１６０0V) 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 25 25mm 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 200 - 1600 REV.2015.02.01 31.0 Dimensions(mm) T max L min d±0.1 14.0 25 1.0 D1±1.0 10.0~13.0 01 | www.spsemi.cn 25D Series Specification and Electrical Characteristics Maximum Varistor Voltage part Number Allowable Voltage Maximum Clamping Voltage Withstanding Surge Current Maximum Energy (10/100μS) Typical Capacitance(R eference) VAC(V) VDC(V) V1mA(V) IP(A) VC(V) I(A) (J) 1KHz(pf) 25D162K 1000 1280 1600(1440-1760) 150 2640 15000 970 450 25D142K 880 1140 1400(1260-1540) 150 2310 15000 850 500 25D122K 750 990 1200(1350-1650) 150 1980 15000 770 550 25D112K 680 895 1100(990-1210) 150 1815 15000 770 600 25D102K 625 825 1000(900-1100) 150 1650 15000 685 650 25D911K 550 745 910(819-1001) 150 1500 15000 620 700 25D821K 510 670 820(738-902) 150 1355 15000 570 800 25D781K 485 640 780(702-858) 150 1290 15000 530 850 25D751K 460 615 750(675-825) 150 1240 15000 510 850 25D681K 420 560 680(612-748) 150 1120 15000 450 950 25D621K 385 505 620(558-682) 150 1025 15000 460 1050 25D561K 350 460 560(504-616) 150 925 15000 440 1150 25D511K 320 415 510(459-561) 150 845 15000 420 1250 25D471K 300 385 470(423-517) 150 775 15000 400 1400 25D431K 275 350 430(387-473) 150 710 15000 380 1500 25D391K 250 320 390(351-429) 150 650 15000 360 1600 25D361K 230 300 360(324-396) 150 595 15000 330 1750 25D331K 210 275 330(297-363) 150 550 15000 300 1900 25D301K 190 250 300(270-330) 150 500 15000 275 2100 25D271K 175 225 270(243-297) 150 455 15000 255 2400 25D241K 150 200 240(216-264) 150 395 15000 220 2650 25D221K 140 180 220(198-242) 150 360 15000 200 2900 25D201K 130 170 200(180-220) 150 340 15000 190 3200 Note：1、Varistor voltage is measured at 0.1 mA for 05D, and at 1 mA for 07D, 10D, 14D, 20D,25D respectively. 2、Operating Temperature Range: －40℃～+85℃ Storage Temperature Range: －40℃～+125℃ REV.2015.02.01 02 | www.spsemi.cn
