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.
The breakover symmetry is within four volts with a typical
breakover voltage of LSDB3 32 V, LSDB4 40 V. These diacs
are intended for use in thyristor phase control, circuits for
lamp-dimming, universal-motor speed controls, and heat
controls.
