Specifications: The APY225G3S is a high-current, high-efficiency PhotoMOS SSR in an SOP-4 package. It is a 1 Form A (SPST-NO) relay rated for 2.5A at 100V AC/DC. It features an ultra-low 60mΩ on-state resistance, provides 2500Vrms isolation, and switches with 1000μs (on) and 60μs (off) times. It operates from -40°C to 85℃ with a 1.28-1.5VDC input. Application Scenarios: Engineered for high-current switching with minimal loss in a compact standard package. Perfect for driving high-power motors, solenoids, and LED arrays in power tools, industrial automation, server PSUs, and electric vehicle subsystems. The low on-resistance ensures high efficiency and reduces thermal management complexity, making it suitable for demanding high-current applications.
