LLDB4 - Bidirectional Diac

Download the LLDB4 datasheet PDF. This datasheet also covers the LLDB3 variant, as both devices belong to the same bidirectional diac family and are provided as variant models within a single manufacturer datasheet.

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. Mechanical Data Case: MiniMELF Glass Case (SOD-80) Polarity: Color band denotes cathod.
