These products fit all modes of control found in
applications such as overvoltage crowbar
protection, motor control circuits in power tools
and kitchen aids, inrush current limiting circuits,
capacitive discharge ignition and voltage
regulation circuits.

These products are particulary adapted for use in
areas where the ambient temperature is high or
the ventilation low, or where an increase of power
density is required.

Through-hole or surface-mount packages provide
performance in a limited space area.
