Littelfuse LX5 0.5A Sensitive-Gate TRIAC

Littelfuse LX5 0.5A Sensitive-Gate TRIAC is a bidirectional solid-state switch series that offers a direct interface to microprocessor drivers in an SOT-23 package. It is designed for low-power AC switching applications like e-valve and AC solenoid drives. The die voltage blocking junctions of the Littelfuse LX5 are glass-passivated to ensure long-term reliability and parametric stability.
