The AQW612EHA is a PhotoMOS solid-state relay in a compact DIP8-pin surface-mount package, integrating both normally open and normally closed contacts. It is designed for AC/DC dual-use loads, handling a load voltage of 60V and a continuous load current of 500mA. This model features a low typical on-resistance of 1 Ω and provides reinforced I/O isolation of 5,000 Vrms. With its high sensitivity and ability to control low-level analog signals, it is well-suited for applications such as power supplies, measuring instruments, security equipment, and industrial plant equipment.
