AQY212GHAX
Overview
The AQY212GHAX is a high-capacity PhotoMOS solid-state relay in a compact 4-pin surface-mount DIP package. It functions as a SPST-NO (1 Form A) switch capable of handling load currents up to 1.1A and load voltages up to 60V AC/DC. This photorelay provides high I/O isolation and is designed as a reliable alternative to traditional mechanical or mercury relays in signal and power switching circuits.
Why Choose This Part
This device offers a high 1.1A load current capacity in a compact form factor while maintaining a very low typical operate current of 1.1mA. It features excellent isolation properties and eliminates the contact bounce and mechanical wear associated with traditional relays, ensuring a long operational lifespan. The 4-SMD package is optimized for automated assembly and space-constrained PCB layouts.
Applications
Key Specifications
Getting Started
To drive the input LED, calculate the series resistor value based on a 1.14V typical forward voltage and your logic level (e.g., 3.3V or 5V), ensuring current exceeds the 1.1mA operate threshold. Use standard SMD reflow soldering profiles as specified for the 4-SMD gull-wing package. Ensure the load remains within the 60V, 1.1A absolute maximum ratings to prevent thermal damage.
