Description
Available either in sensitive (TS8) or standard
(TN8 / TYN) gate triggering levels, the 8 A 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.
