Solid State Relays are electrical equipment for controlling currents, used to switch high voltage AC circuits. The PR39MF12NSZ is a particular type of SSR that combines a low voltage DC input voltage with an AC load voltage. It utilizes a powerful, optically-isolated MOSFET gate, and features fast switching and superior heat resistance, while still being physically small and light.

Application Field

PR39MF12NSZ SSRs are used in a variety of applications that require fast switching with high precision and superior heat resistance. Examples include motor drives, circuit protection, temperature and pressure control systems, building automation systems, and medical equipment.

Due to their small size and light weight, they are also well suited for use in portable and mobile equipment. Some applications that commonly use SSRs like the PR39MF12NSZ include power supplies, medical equipment, consumer electronics, solar cells, and communications devices.

Working Principle

The PR39MF12NSZ SSR is connected between an input voltage and a load voltage. The input voltage is typically a low voltage DC supply, while the load voltage is typically an AC power supply. The device functions by utilizing an optically-isolated MOSFET gate.

When the input voltage is high, the MOSFET gate switches to a closed state, allowing current to flow through the load. When the input voltage is low, the MOSFET gate switches to an open state, preventing current from flowing through the load. This allows the device to quickly switch between on and off states, while maintaining high precision and low power consumption.

PR39MF12NSZ Solid State Relays also feature a superior heat resistance compared to other SSRs, allowing them to operate in high temperatures for longer periods of time. This makes them ideal for applications with rapid thermal cycling, such as circuit protection and motor drives.

Due to their small form factor and impressive performance, PR39MF12NSZ Solid State Relays are becoming increasingly popular among engineers and technicians looking to save space and ensure fast, reliable switching.
