Specifications: The OPT1253G2EH is a medium-power PhotoMOS SSR capable of handling 1.1A at 400V (AC/DC), packaged in SMD-4. It has a low 0.48Ω on-state resistance and 5000Vrms isolation. Switching characteristics are 1.5ms turn-on and a fast 30μs turn-off. It is designed for wide-temperature operation (-40°C to 85°C) with a 1.32-1.55VDC input range.
Application Scenarios: Suited for switching higher-current loads at line voltages. Common applications include appliance motor control (fans, pumps), solid-state lighting ballasts, industrial contactor coil drivers, and as the main switch in offline SMPS (Switch-Mode Power Supplies) or UPS (Uninterruptible Power Supply) battery charging circuits.
