WEJ ELECTRONIC CO.,LTD The three layer ,two terminal,axial lead,hermetically sealed diacs are designed specifically for triggering thyristors.They demonstrate low breakover current at breakover voltage as they withstand peak pulse current The breakover symmetry is within three volts(DB3,DC34,DB4)or four volts(DB6).These diacs are intended for use in thyrisitors phase control,circuits for lamp dimming.universal motor speed control,and heat control. JF S DB3/DC34/DB4/DB6 are bi-directional trigged diode designed to operate in conjunction with Triacs and SCR s SILICON BIDIRECTIONAL DIAC FEATURE ABSOLUTE RATINGS(LIMITING VALUES) Dimensions in inches and (millimeters) 1.083(27.5) MIN 0.150(3.8) MAX 0.020(0.52) MAX DIA DO-35(GLASS) 1.083(27.5) MIN 0.079(2.0) MAX DIA Symbols Parameters Value UnitsDB3 DC34 DB4 DB6 150 2.0 2.0 2.0 16 mW A O C Pc ITRM T /TSTG J Power Dissipation on printed Circuit(L=10mm) Repetitive peak on-state Current Storage and Operating Junction Temperature T = 50 A O C tp=10 s F=100Hz -40 to+125/-40 to 110
