BIDIRECTIONAL DIACS
POWER DISSIPATION 150 mW
FEATURES
DO- 41
●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
