FEATURES

hermetically sealed diacs are designed specifically for

triggering thyrisitors .The demonstrate low breakover current.

The breakover symmetry is within three volts(DB3,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
