Series PVA33NPbF
Microelectronic Power IC
HEXFET® Power MOSFET Photovoltaic Relay
Single-Pole, Normally-Open, 0-300V AC/DC, 150mA
General Description
The PVA33 Series AC Relay (PVA) is a single-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 PVA33 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 PVA33 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 500Hz 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 thru-hole or
surface-mount (“gull-wing”) leads, in plastic shipping
tubes.
