Triac MSKSEMI BT131W-600D-MS designed for switching in motor control and light dimmer applications

Product Overview

The BT131W-xxxx-MS series from MSKSEMI are high-performance triacs designed for general-purpose switching applications. These triacs offer direct interfacing to logic-level ICs and low-power gate drive circuits, featuring high blocking voltage capability and planar passivation for enhanced voltage ruggedness and reliability. They are suitable for triggering in all four quadrants, making them ideal for motor control, light dimmers, and home appliance phase control operations.
