FEATURE

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
