| DB3,DB4,DB6 SILICON BIDIRECTIONAL DIACS FEATURES Three way layer two terminal, axial lead , POWER DISSIPATION DO - 35 150 mW hermetically sealed diacs are designed specifically for triggering thyrisitors .The demonstrate low breakover current. The breakover symmetry is within three volts(DB3,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 This diocle is also avaiable in the DO-35case. .020 TYP.
