What is a Solid-State Relay?
A solid-state relay (SSR) is an electronic switching device that controls a load without moving parts. It offers faster switching, longer life, and silent operation compared to mechanical relays. SSRs are ideal for small-signal and sensitive applications.
Key Features
- Solid-state, no mechanical wear
- DIP 4-pin compact package
- High isolation between input and output (1500Vrms)
- Low on-resistance for energy efficiency
- Silent, high-speed switching
- Low input control current
- Ideal for signal-level control
Benefits of Solid State Relay
The AQY212EH offers reliable and long-lasting performance in environments where mechanical relays may fail due to wear and tear. Its small size and low power requirements make it suitable for space-sensitive applications on PCBs. It ensures smooth, noiseless, and energy-efficient operation.
Key Benefits:
- Longer lifespan than traditional relays
- No clicking sound – completely silent
- Small and lightweight for compact devices
- High switching reliability
- Energy-efficient performance
- Suitable for sensitive signal control
Applications
- Telecommunication equipment
- Measurement instruments
- Security devices
- Industrial automation
- Signal switching in control systems
- Audio/visual electronic equipment
How to Use?
To use the AQY212EH, mount it on a PCB as per your design, and connect the input side to a 4–6V DC control circuit. The load side can control up to 60v with a maximum current of 120mA. Ensure isolation between input and output. The relay switches silently and efficiently when the control voltage is applied.
Cautions
- Do not exceed voltage or current ratings
- Avoid exposure to high humidity or dust
- Ensure proper PCB layout to prevent heat build-up
- Use within the recommended operating temperature
- Handle gently to prevent static discharge damage
