Specifications: The APW210S is a dual-channel PhotoMOS SSR in a standard SOP-8 package. Each channel is rated for 120mA at 350V (AC/DC), with a 17Ω on-state resistance and 2500Vrms isolation. It features symmetrical 50μs switching for both on and off states. The device operates from -40°C to 85°C with 1.2-1.4VDC control.

Application Scenarios: A cost-effective dual-channel relay for medium-voltage signal switching. Commonly used in data acquisition boards, industrial communication interfaces, and consumer appliance control circuits where two isolated switches are needed and the SOP-8 package is preferred for manufacturability.
