Specifications: The APW212EH is a dual-channel (2 Form A) PhotoMOS SSR in an SMD-8 package. Each channel is a 1 Form A (SPST-NO) switch rated for 500mA load current and 60V load voltage (AC/DC). Each channel has a 1Ω on-state resistance, provides 5000Vrms isolation, and switches with 500μs (on) and 350μs (off) times. It operates from -40°C to 85℃ with a 1.2-1.5VDC input range. Application Scenarios: Ideal for medium-current dual switching in compact, surface-mount designs. Common applications include driving two independent loads (e.g., LEDs, small motors, solenoids) in consumer electronics and industrial controls, dual-channel power supply enable/disable, signal multiplexing in test equipment, and providing isolated I/O expansion in embedded systems, where its SMD package saves valuable board space.
