Specifications: The APY215E is a through-hole DIP-4 PhotoMOS SSR, configured as 1 Form A (SPST-NO). It is rated for 600mA at 100V AC/DC. It features a low 0.8Ω on-state resistance, provides 5000Vrms isolation, and has switching times of 1500μs (turn-on) and 80μs (turn-off). It is designed for wide-temperature operation from -40°C to 85℃ and uses a 1.2-1.4VDC control signal.

Application Scenarios: A versatile and robust relay for medium-current switching where through-hole mounting is preferred for prototyping, serviceability, or mechanical reasons. Common applications include industrial control outputs for small actuators and contactors, HVAC system fan and pump relays, appliance motor control, power management in industrial equipment, and as a reliable interface between microcontrollers and various AC/DC loads in legacy or service-oriented designs.
