BL GALAXY ELECTRICAL
SILICON BIDIRECTIONAL DIACS
DB3.DB4
VOLTAGE RANGE: 28-45 V
FEATURES
The three layer,two termnal,axial lead,hermetically
1111sealed diacs are des igned s pecifically for triggering
1111thyristors .They demonstrate low breakover current at
1111breakover voltage as they withs tand peak pulse
1111current,The breakover s ymmetry is within three
1111volts(DB3,DB4). These diacs are intended for use in
CCCthyrisitors phase control,circuits for lamp dimming,
FFFI universal motor speed control,and heat control.
