features
●three way layer two terminal, axial lead ,
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
●this diocle is also avaiable in the do-41case.
