DESCRIPTION
Available either in sensitive or standard gate
triggering levels, the 8A SCR series is suitable
to 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.
Available in through-hole or surface-mount
packages, they provide an optimized performance
in a limited space.
