PVD (Photovoltaic Diode) Array Chips for Solid State Relays
PVD stands for photovoltaic diode, which is a semiconductor device that converts light into electricity. PVD array chips for solid-state relays are used to isolate high voltage from the control circuit of a solid-state relay, providing a safe and reliable way to switch high voltage AC or DC loads.
The PVD array chip consists of a number of PVD cells connected in series and parallel to provide the required output voltage and current. When light strikes the surface of the PVD cell, it generates a current that flows through the series and parallel connections to produce an output voltage.
The PVD array chip is typically made of a high-performance, high-reliability semiconductor material such as silicon, gallium arsenide, or indium phosphide. The chip is packaged in a hermetically sealed enclosure with an anti-reflective coating on the surface to maximize light absorption. The PVD array chip can be designed to operate at a specific wavelength range, allowing it to be optimized for specific applications such as UV sensing, visible light sensing, or IR sensing.
