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.
