Specifications: The APW212S is a dual-channel (2 Form A) PhotoMOS SSR in a standard SOP-8 surface-mount package. Each channel is a 1 Form A (SPST-NO) switch rated for 200mA at 60V AC/DC. Each channel has a 2Ω on-state resistance, provides 2500Vrms isolation, and features fast, symmetrical 50μs switching for both on and off states. It operates from -40°C to 85℃ with 1.2-1.4VDC control. Application Scenarios: A versatile, cost-effective dual-channel relay for general-purpose low-power switching. Suitable for signal multiplexing in test equipment, isolated digital I/O expansion, dual load driving (e.g., LEDs, indicators) in consumer and industrial electronics, communication port control, and as a reliable interface in power management circuits, benefiting from the widespread availability and ease of assembly of the SOP package.
