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
Rectier’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.
