Specifications

Silicon Bidrectional Diac DB3A A-405

Products Description 

The three layer, two termnal, axial lead, hermetically sealed diacs are designed specifically for triggering thristors. They demonstrate low breakover current at breakover voltage as they with stand peak pulse current, the breakover symmetry is within three volts.These diacs are intended for use in thyrisitors phase control, circuits for lamp dimming universal motor speed control, and heat control.
