LLDB4 Datasheet - Olitech Electronics Co.Ltd

Features
   The 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 three volts (DB3,DB4). These diacs are intended for use in thyrisitors phase control , circuits for lamp dimming,universa motor speed control ,and heat control.
