DB3, DB4, DC34 SILICON BIDIRECTIONAL DIACS The glass passivated, 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.
These diacs are intended for use in thyristor phase control, circuits for lamp-dimming, universal-motor speed controls, and heat controls.
