Technical Specifications

The PS7122AL-1C-E3 features a high isolation voltage, typically several kilovolts. The on-resistance is low, typically a few ohms. It has a high surge current capability, allowing it to handle transient loads. The zero-crossing detection minimizes switching noise and extends the life of the load. The operating temperature range is typically from -40°C to +85°C. The package is often a small surface-mount package.

The PS7122AL-1C-E3 from NEC is a versatile solid-state relay suitable for a wide range of applications requiring reliable and isolated switching of AC or DC loads. Its high isolation voltage, low on-resistance, and zero-crossing detection make it a preferred choice for industrial control and automation systems.
