Introduction

The PVAZ172N optical relay is a single-pole normally-open solid-state relay that can replace electromechanical relays used for general switching of DC and AC loads. It uses the HEXFET power MOSFET from International Rectifier as the output switch, which is driven by an integrated-circuit photovoltaic generator with a new structure. The output switch is controlled by the radiation emitted from a GaAlAs light-emitting diode (LED), which is optically isolated from the photovoltaic generator. These devices overcome the limitations of electromechanical and reed relays and offer the advantages of solid-state technology, such as high sensitivity, miniaturization, no contact bounce, long service life, insensitivity to external magnetic fields, resistance to shock and vibration, and inherent high reliability. They are well-suited for switching high currents or low-level signals without distortion or injection of electrical noise. These relays are packaged in an 8-pin plastic DIP package and are available in through-hole or surface-mount ("gull-wing") pin versions, supplied in plastic shipping tubes.
