Specifications: The APW251G2EH is the surface-mount SMD-8 version of a dual-channel, high-current PhotoMOS SSR. 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 has switching times of 800μs (on) and 20μs (off). It operates from -40°C to 85℃ with 1.2-1.4VDC control.

Application Scenarios: Engineered for the same high-performance dual-channel switching as the DIP version but in a compact SMD package for modern, high-density designs. Perfect for space-constrained applications in servers, telecom blades, advanced automotive control units, compact industrial drives, and portable high-power equipment, delivering maximum current handling and efficiency in a minimal footprint.
