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.
