PVD13N

The PVD13N Series DC Relay (PVD) is a single-pole, normally open, solid-state replacement for electromechanical relays used for general purpose switching of analog signals. PVD13N utilizes International Rectifier's HEXFET power MOSFET as the 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 PVD13N 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 PVD13N can switch analog signals from thermocouple level to 100 Volts peak DC. Signal frequencies into the RF range are easily controlled and switching rates up to 450Hz are achievable. The extremely small thermally generated offset voltages allow increased measurement accuracies.

These relays are packaged in 8-pin, molded DIP packages and available with either through-hole or surface-mount ("gull-wing") leads, in plastic shipping tubes.
