The MCR18 with SOT-23-3L TRIACs is a low power sensitive gate, roughmate package, bidirectional electronic component manufactured by Weida Semiconductor. It is an integrated device in a three-pin SOT-23-3L package and it is RoHS compliant. The MCR18 uses a sensors that detects when the gate current is at a higher level than that of the main and/or holding current. When this happens, the integrated device switches on to allow the flow of current in either direction, depending on the voltage across the part. The MCR18 is designed for use in lighting control, motor control and other AC power control applications. It is capable of handling current from 3mA to 50mA continuous and up to 100mA peak. It has a blocking voltage range from 5V to 400V.
