GA5-4A25 is a solid state relay from the GA5 series designed for general purpose AC switching applications. It features an economical triac output configuration with a maximum on-state current rating of 25 Arms and an output voltage rating of 250 VRMS maximum (±400 Vpeak off-state). The device provides 4kV optical isolation between input and output, superior false turn-on immunity, and includes an RC snubber network for inductive load protection. With a control voltage range of 90-280 VAC, a maximum 1-cycle surge capability of 250 Apeak, and an on-state voltage drop of 1.6 Vpeak, this relay is well-suited for industrial automation, HVAC systems, and general switching applications requiring reliable AC load control.
