1 ? 2016 littelfuse, inc. revised: 11/28/16 kxxx0yu sidac series description the sidac is a silicon unilateral voltage triggered switch. upon application of a voltage exceeding the sidac breakover voltage point, the sidac switches on through a negative resistance region to a low on-state voltage. conduction continues until the current is interrupted or drops below the minimum holding current of the device. sidacs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments. features schematic symbol applications suitable for capacitor-discharge hv generator circuit ? rectifed ac/dc circuit oriented ? triggering voltage of 75v to 260v ? rohs compliant symbol parameters test conditions min max unit v bo breakover/trigger voltage k0820yurp 75 90 v k0900yurp 79 97 k1050yurp 95 110 k1100yurp 104 118 k1200yurp 110 125 k1300yurp 120 138 k1400yurp 130 146 K1500YURP 142 157 k1800yurp 167 183 k2000yurp 190 210 k2200yurp 210 230 k2300yurp 220 240 k2400yurp 230 250 k2500yurp 240 260 v drm repetitive peak off-state voltage k0820yurp 70 v k0900yurp 70 k1050yurp 90 k1100yurp 90 k1200yurp 100 k1300yurp 110 k1400yurp 115 K1500YURP 120 k1800yurp 150 k2000yurp 170 k2200yurp 190 k2300yurp 200 k2400yurp 210 k2500yurp 220 electrical specifcations (t j = 25c, unless otherwise specifed) rohs specifcations are subject to change without notice. teccor ? brand thyristors standard unidirectional sidacs
