Specifications: The APY215EH is a compact SMD-4 PhotoMOS SSR designed for medium-current switching. This 1 Form A (SPST-NO) device handles 600mA at up to 100V AC/DC. It features a low 0.8Ω on-state resistance, 5000Vrms isolation, and switching times of 1500μs (on) and 80μs (off). It is built for harsh environments with an operating range of -40°C to 85°C and uses a 1.2-1.4VDC control signal. Application Scenarios: Perfect for space-constrained applications requiring robust current handling and isolation. It is used in industrial automation for driving small motors and actuators, in HVAC systems for fan and pump control, in telecom power distribution, in automotive body electronics, and in smart home devices for appliance control, offering silent and reliable operation.
