Series PVA33NPbF

Microelectronic Power IC

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.

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.
