Specifications: The APY111G5S is an ultra-high-current PhotoMOS SSR for low-voltage applications. Rated for 5A at 20V (AC/DC) in an SOP-4 package, it features an extremely low 0.2Ω on-state resistance and 2500Vrms isolation. It switches with 500μs (on) and 30μs (off) times. Designed for harsh environments (-40°C to 85°C), it uses 1.2-1.4VDC for control.

Application Scenarios: Engineered for the highest current density in its package class. Ideal for high-power DC motor control (e.g., in power tools, e-bikes), server blade power distribution, high-current LED drivers, and as a main battery disconnect switch in electric vehicles or energy storage systems, where minimizing voltage drop is paramount.
