APY212G APY212G1S SOP4 Car ECU Board Solid-State Relay Optocoupler Chip

APY212G/APY212G1S SOP4 automotive optocoupler chip featuring a single-channel normally-open Photo-MOS solid-state relay. Supports 1.1A/60V load driving, 2.5kV electrical isolation, and low on-resistance (130mΩ); operates without mechanical contacts or arcing. Isolates low-power MCU signals to control vehicle body lighting, door locks, sensors, and infotainment I/O loads; prevents high/low-voltage crosstalk; wide operating temperature range (-40°C to +85°C) suitable for automotive body electronics.
