Specifications: The ADW221S is a PhotoMOS SSR in a larger SOP-16 package, rated for 200mA at 60V (AC/DC). It has a 3Ω on-state resistance, provides 2500Vrms isolation, and switches in 50μs (on) and 40μs (off). It operates from -40°C to 85°C with 1.2-1.4VDC control.

Application Scenarios: The SOP-16 package may offer different pin spacing or internal configuration. Suitable for applications requiring the specific footprint or enhanced creepage/clearance. Common in legacy or specific layout designs for industrial control boards, test equipment, and communication interfaces where the SOP-16 form factor is specified.
