Power MOSFET Photovoltaic Relay
Dual-Pole, Normally-Open
0-300V AC/DC, 165mA
General Description
The PVR33 Series AC/DC Relay is a dual-pole,
normally open, solid-state replacement for
electromechanical relays used for general purpose
switching of analog signals. It utilizes International
Rectifier’s HEXFET power MOSFETs as the output
switches, 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 PVR33 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 PVR33 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 350Hz are
achievable. The extremely small thermally generated
offset voltages allow increased measurement
accuracies.
These relays are packaged in 16-pin, molded DIP
packages and available with thru-hole leads, in
plastic shipping tubes.
