300 V, 50 mA single-polePhotovoltaic Relayin a mod. 8-pin SMT Package. This normally opensolid-state relaycan replace electromechanical relays used for general purpose switching of analog signals. The PVA30 Series combines very low solid-state output capacitance, very high off-state resistance and very fast response times. These Photovoltaic Relays are designed specifically to accurately switch low-level signals in highperformanceinstrumentation systems. The PVA30 Series overcomes the limitations of both conventional electromechanical and reed relays by offering the solid state advantages of long life, fast operating speed, low pick up power, bounce-free operation, low thermal offset voltages and miniature package. These advantages allow product improvement and design innovations in many applications such as process control, multiplexing, automatic test equipment and data acquisition. The PVA30 can switch analog signals from thermocouple level to 300 Volts peak AC or DC polarity. Signal frequencies into the RF range are easily controlled and switching rates up to 1.7kHz are achievable. The extremely small thermally generated offset voltages allow increased measurement accuracies.
