SILICON BIDIRECTIONAL DIAC

LLDB3/LLDC34/LLDB4/LLDB6

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 LLDB3 32 V, LLDB4 40 V. These diacs

are intended for use in thyristor phase control, circuits for

lamp-dimming, universal-motor speed controls, and heat

controls.
