Overview

The AQW212EHAZ is a dual-channel PhotoMOS solid-state relay containing two independent SPST-NO (1 Form A) circuits in a single 8-SMD package. It utilizes an LED input and a MOSFET output to provide 5,000 V of I/O isolation, allowing it to control both AC and DC loads up to 60V and 500mA. This component is designed for high-speed, high-sensitivity switching of low-level analog signals without the mechanical wear of traditional relays.

Why Choose This Part

This device offers a high 5,000 V isolation voltage and an extremely low off-state leakage current of 1 microamp. Its solid-state construction eliminates contact bounce and mechanical wear, providing a significantly longer service life and faster response times than electromechanical alternatives.

Applications

Analog Signal Switching
Precisely switching low-level measurement signals in data acquisition systems with minimal offset voltage.
Industrial I/O Modules
Providing isolated digital outputs for PLC systems to interface with 24V or 48V logic.
Telecommunications Equipment
Used for line switching and hook status detection where high isolation and reliability are required.
Test and Measurement
High-density switching matrices in automated test equipment (ATE) due to its small 8-pin surface mount footprint.

Getting Started

To drive the input side, ensure the LED forward current is limited by a series resistor to meet the 1.14V typical forward voltage requirement. The dual-channel configuration allows for independent control of two loads or can be utilized as a 2 Form A relay by tying the inputs together in parallel or series.
