Specifications: The APW212E is a dual-channel (2 Form A) PhotoMOS SSR in a DIP-8 through-hole 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℃ to 85℃ with a 1.2-1.5VDC input range. Application Scenarios: A versatile dual-channel relay for medium-current switching, ideal for through-hole designs. Common applications include driving two independent loads in industrial control panels, redundant power control in legacy systems, test equipment channel switching, educational and prototyping boards, and as a reliable interface in power over Ethernet (PoE) midspans and other network hardware, offering the serviceability and thermal mass of a DIP package.
