AQV212SX
Overview
The AQV212SX is a 6-pin SOP PhotoMOS solid-state relay designed for switching AC or DC loads up to 60V at 500mA. It utilizes a photo-coupled LED to drive a MOSFET output, providing 1500V isolation between the input and output circuits. As a 1 Form A (SPST-NO) device, it offers a reliable, silent alternative to mechanical relays with significantly lower drive current requirements.
Why Choose This Part
This photorelay features an extremely low typical operate current of 0.7mA, allowing it to be driven directly by standard microcontroller GPIO pins without an external buffer. The 6-pin SOP package provides a compact footprint while maintaining 1.5kV isolation, and its solid-state construction eliminates the contact bounce and mechanical wear associated with traditional electromechanical relays.
Applications
Key Specifications
Getting Started
To drive the input, treat the control pins like a standard LED by using a current-limiting resistor to target the 3mA maximum operate current from a 3.3V or 5V logic source. Ensure the load remains within the 0V to 60V range and does not exceed the 500mA continuous load current rating. For PCB layout, maintain proper creepage and clearance distances under the 6-SOP package to preserve the 1500V isolation rating.
