TYN612M
12 A SCR
Main features
Description
The TYN612M SCR is suitable to fit modes of
control found in applications such as voltage
regulation circuits for motorbikes, overvoltage
crowbar protection, motor control circuits in power
tools and kitchen aids, inrush current limiting
circuits, capacitive discharge ignition.
The insulated fullpack package allows a back to
back configuration.
