DB3M.DB4M
SILICON BIDIRECTIONAL DIACS
VOLTAGE RANGE: 28-45 V
FEATURES
The three layer,two termnal,hermetically sealed diacs
are designed specifically for triggering thyristors.
They demonstrate low break over current at break
over voltage as they withstand peak pulse current,
The breakover symmetry is within three volts(DB6).
These diacs are intended for use in thyrisitors
phase control,circuits for lamp dimming,universal
motor speed control,and heat control.
