The PVX6012 Photovoltaic Relay is a single-pole, normally open solid-state relay that can replace electromechanical relays in many applications. It utilizes an IGBT output switch, driven by an integrated circuit photovoltaic generator of novel construction. The output switch is controlled by radiation from a GaAlAs light emitting diode (LED) which is optically isolated from the photovoltaic generator. The PVX6012 is ideally suited for switching medium power loads. It offers high operating speed, low and stable on-state voltage drop as well as low off-state leakage current.
