LLDB-3_15 Datasheet, PDF (1/1 Pages) GOOD-ARK Electronics – Trigger Diodes

Features
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
LLDB-3 32 volts, LLDB-4 40 volts. These diacs are intended for
use in thyristor phase control, circuits for lamp-dimming, universal-
motor speed controls, and heat controls.
Good-Ark's LLDB-3 and LLDB-4 are bi-directional trigger diodes
designed operate in conjunction with all of Good-Ark Electronics'
Triacs and SCR's.
