Specifications: The APW412S is a dual-channel Normally Closed (SPST-NC) SSR in a standard SOP-8 package. Each channel is rated for 400mA at 60V (AC/DC), with a 0.8Ω on-state resistance and 2500Vrms isolation. Switching times are 500μs (open) and 250μs (close). The device operates from -40°C to 85°C with 1.2-1.4VDC control.

Application Scenarios: A cost-effective, industry-standard package for dual NC switching. Common in appliance safety circuits, industrial emergency stop modules, and power supply protection circuits where two independent fail-safe paths are implemented on a single chip.
