ELECTRICAL CHARACTERISTICS

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
