The BT131-89-2L with SOT-89-2 TRIACs ROHS is a surface mount device from Kang Yang, designed to provide power management solutions and trigger and control signal switching functions. The device is constructed from two composite semiconductor layers, one a gate and the other a main conduction path. This features a thermal expansion coefficient and low thermal resistance, yielding excellent thermal conductivity and stability. This TRIAC is capable of switching AC power from a few mA up to 6A. It is RoHS compliant, and offers high efficiency with minimal power loss, due to its low capacitances. With a wide range of operational voltages, the BT131-89-2L TRIACs are an ideal solution for consumer electronics applications.
