The PVN012A Series Photovoltaic Relay at 50 milliohms features the lowest possible on-state resistance in a miniature package — lower than a comparable reed relay. The PVN012A is a single-pole, normally open solidstate relay. It utilizes a HEXFET® MOSFET 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. These units exceed the performance capabilities of electromechanical relays in life, sensitivity, stable onresistance, miniaturization, magnetic insensitivity and ruggedness. They are ideally suited for switching high currents or low level signals without distortion or injection of electrical noise.
