Specifications: The OPT2251G2E is a dual-channel (2 Form A), high-current PhotoMOS SSR in a through-hole DIP-8 package. Each channel is a 1 Form A (SPST-NO) switch rated for 2.5A at 40V AC/DC. Each channel features an ultra-low 60mΩ on-state resistance, provides 3750Vrms isolation, and switches with 800μs (turn-on) and a very fast 20μs (turn-off) time. It is designed for reliable operation from -40°C to 85℃ with a 1.2-1.4VDC control input.
Application Scenarios: Designed for high-current dual-switching applications where the thermal mass and mechanical robustness of through-hole mounting are beneficial, such as in prototyping or high-reliability systems. Ideal for industrial motor control boards, high-current power supply modules, battery test equipment, robotics driver circuits, and as a robust switch in electric vehicle auxiliary systems, combining high efficiency with excellent thermal performance.
