MA64

Silicon Bidirectional Diacs

VOLTAGE RANGE: 28-45 V

DO-35

Features

The three layer,two termnal,axial lead,hermetically

1111sealed diacs are designed specificallyfor triggering

1111thyristors.They demonstrate low breakover current at

1111breakover voltage as theywithstand peak pulse

1111current,The breakover symmetry is within three

1111volts(MA64). These diacs are intended for use in

CCCthyrisitors phase control,circuits for lamp dimming,

FFFI universal motor speed control,and heat control.
