Specifications: The APV256BE is a medium-voltage, medium-current PhotoMOS SSR in a DIP-6 package. This 1 Form A (SPST-NO) device handles 400mA load current at up to 600V AC/DC. It has a 4Ω on-state resistance and provides 5000Vrms isolation. Switching times are 700μs (turn-on) and 70μs (turn-off). It operates reliably from -40°C to 85°C with a 1.1-1.7VDC control input. Application Scenarios: Ideal for applications requiring robust isolation at several hundred volts. Common uses include industrial motor drive auxiliary circuits, power supply control and monitoring, HVAC system controls, industrial lighting ballasts, and as an isolation switch in renewable energy systems (solar inverter auxiliary power). The through-hole DIP package offers good thermal performance and mechanical stability for industrial environments.
