AQV224NSZ is a PhotoMOS solid-state relay designed for AC/DC dual-use switching applications with a 400V load voltage rating. This miniature SOP6-pin device features low on-resistance (typical 30O at 5mA), 1500Vrms I/O isolation voltage, and supports continuous load current up to 40mA (A connection). The relay operates with LED forward current of 5-30mA and offers an operating temperature range of -40°C to +85°C. With its compact dimensions of 4.4mm × 6.3mm × 2.1mm and low-level off-state leakage current, this PhotoMOS relay is ideal for telephones, measuring instruments, computers, industrial robots, and high-speed inspection machines where reliable signal switching is required.
