What is a Solid-State Relay?

A solid-state relay (SSR) is an electronic switch that uses semiconductor components instead of mechanical contacts to control loads. It provides silent, fast, and long-lasting operation, making it ideal for sensitive and frequent switching applications.

Key Features

• DIP 4-pin compact package
• AC load switching up to 2A
• Zero-cross switching reduces electrical noise
• 4000Vrms input-to-output isolation
• Triac output for reliable switching
• Low input current requirement
• Silent operation with no moving parts

Benefits of Solid State Relay

The AQH2223 solid-state relay is ideal for designers seeking a quiet, reliable, and durable alternative to mechanical relays. It offers superior isolation, reduced EMI thanks to zero-cross switching, and minimal power loss. The relay’s compact size makes it suitable for tight PCB designs, especially in consumer electronics and control systems.

Key Benefits:

• High electrical isolation ensures safe operation
• Compact for space-constrained boards
• Ideal for frequent switching tasks
• Long-lasting with no mechanical wear
• Reduces noise and interference in sensitive circuits
• Reliable AC load control with low trigger current

Applications

• Home appliances (washing machines, microwave ovens)
• Industrial automation systems
• Smart HVAC and lighting systems
• Test and measurement equipment
• Motor and pump control panels
• Consumer electronics

How to Use?

To use the AQH2223, solder the relay onto your PCB with the correct orientation. Connect the input terminals to a 5V DC signal circuit and the output side to an AC load (up to 2A). When the input signal is applied, the triac inside the relay switches on the AC load using zero-cross technology for minimal interference.

Cautions

• Do not exceed the rated load current or voltage
• Ensure adequate heat dissipation during high-load operation
• Protect against overvoltage conditions with appropriate snubber circuits
• Avoid reverse polarity at input
• Store in a dry, dust-free environment
