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,DC34,DB4)or four volts(DB6).These diacs are
intended for use in thyrisitors phase control, circuits for lamp dimming,universal
motor speed control, and heat control.
JF's DB3/DC34/DB4/DB6 are bi-directional trigged diode designed to operate
in conjunction with Triacs and SCR's
